What's Your Question?

10 Interview Questions to Prepare For

Half the challenge of going for a job interview is not knowing what to expect. Many otherwise highly qualified candidates may be caught off-guard by questions they don’t know how to answer. So, to help you prepare, here are the top 10 interview questions you could be asked — along with some excellent answers.

Tell Me About Yourself.

You’ll probably be asked this at the outset. It’s kind of meant as an ice-breaker, even if the thought of it makes you shudder. Don’t be afraid to be personal. Talk about your hobbies and motivations, and feel free to showcase your personality. But don’t go on too long. And try to relate what you say to the job.

Why Do You Want This Job?

No, the answer is not “for the money.” Even if it is. Interviewers expect candidates to show off their knowledge of the company, and what appeals to them about the position they’ve applied for. So you should really know the ins and outs of the role and why you (might) want to work for that particular company.

What Is Your Greatest Weakness?

There’s an art to answering this question; it involves spinning your weakness as a strength. You might say, for example, that you can be a bit of a perfectionist. But if you do, it’s sensible to add that your drive to meet deadlines helps you to manage your time.

What Is Your Greatest Strength?

You might be proud of your crocheting skills, but is it relevant to the job? Always remember that you’re (probably) not the only shortlisted candidate. So if your greatest strength is swimming 50 lengths in a lunch break and another’s being a “people person,” who’s going to get the job in HR?

How Do You Handle Stress?

Bearing in mind that a smoke and a drink probably isn’t an acceptable answer, try to come up with a concrete example of how you’ve dealt with pressure in the workplace in the past. Telling them you never get stressed isn’t necessarily a good idea. Even if they believe you, they might just assume you’ve only worked in cushy environments.

Why Should I Hire You?

They’re asking for your sales pitch with this one. Don’t be modest. But don’t be arrogant either. Recap the highlights of your resume and emphasize any qualifications and experience that meet the requirements for the job. And finish with your own USP.

Where Do You See Yourself Five Years From Now?

Maybe this job is just a stopgap. Maybe in five years’ time, you won’t want anything to do with this company. But whatever you do, don’t tell them that. Instead, talk about your career progression goals and how your advancement will also be theirs. They might like to hear that you want to specialize and take on more responsibilities.

What Are Your Salary Expectations?

This is a horrible question. Not only can it knock you out of the contest if you quote a figure that’s a little too high; but employers can also hold candidates to a figure that’s well below average. Prior research is key. Find out the industry standard. And give a salary range instead of an exact sum — or, if possible, defer the question to your second interview.

Why Did You (or Will You) Leave Your Last (or Current) Job?

This isn’t an opportunity to rail against another employer. That would just seem disloyal. Even if you’re leaving under negative circumstances, focus your answer on the future. Talk about new opportunities. But also be factual and pragmatic.

Do You Have Any Questions for Me?

No, the interview hasn’t ended. This question is just as important. Many employers ask this to gauge how interested you really are in their company. So you might want to ask about the management style, or what your predecessor went on to do. You could also ask about the prospects for career advancement.

It is one of the most crucial business analyst interview questions asked by a recruiting manager to assess your work strategy, teamwork, and project management skills.

To answer this question, you can explain the general steps you follow with standard deliverables. For example, if you have managed the planning phase of a project, you could mention deliverables like a requirements management plan, work breakdown structure, or a communication plan.

Each business faces different situations and has distinct needs, but these fundamental steps are essential to achieve a task successfully:

Your hiring manager may ask this role specific question to ensure that you understand standard business analysis documents and how to apply them to a client's case. You must list your past experiences and examples to validate your credibility and value. 

The most used diagram models by business analysts are:

  • Flowcharts – These are the diagrammatic depiction of the complete flow of the system. They make it easy for all the stakeholders, whether technical or technical, to understand the operation. 
  • Activity Diagram – These diagrams illustrate the diverse activities and their flow across various departments. 
  • Use case Diagrams – These diagrams model the functionality of a system using a set of actions, functions, and services that the system/project needs to perform. 

These diagrams are beneficial in visualizing the functional requirements of a system and finalizing development priorities. They also identify any external/internal factors that should be considered as they can influence the project.

  • Sequence Diagrams -  These diagrams illustrate the interaction between different objects and the time sequence of the message flow between them.
  • Collaboration Diagrams - These are also called interaction or communication diagrams. They are the illustration of the relationships and interactions among software objects in the Unified Modeling Language.

Many diagrams can be used in business analysis, and you can say that you follow a more coherent approach of merging different models to produce results.

25. What is the exception and alternate flow in a use-case diagram? How are they different from basic flow?

  • The basic flow is the representation of the operation of activities as required by the company.
  • Alternate flow is the representation of actions or activities other than basic flow. It leads to achieving the goals of use-cases using different steps.
  • Exception flow represents the actions executed in case of errors. It leads to NOT achieving the goal of a use case.

26. What are personas, and how they are useful in user-centred design methodology?

Personas are created in place of real users to understand their behavioral patterns in different scenarios. In user-centered design methodology, a system is developed, keeping the viewpoint of end-users in mind. Personas help create such systems.

27. Define analytical reporting.

A business analyst needs to comprehend the significance and drawbacks of analytical reporting, and you must be ready with an answer during your business analyst interview.

You can start your answer by a brief definition of analytical reporting. It is a type of business reporting that offers data analysis, information, and recommendations. The recommendations are the critical attributes that make it different from informational reporting. 

After that, you can describe the impact your analytical reporting made in previous roles. Focus on showing how you can create recommendations from data sources and demonstrate your analytical skills.

28. If there are multiple stakeholders in a project, how do you influence them? Also, explain how you would work with a difficult stakeholder?

With this type of business analyst interview questions, the recruiter is trying to understand how you implement your various competencies, especially communication, negotiation, problem-solving, decision making, influencing, and collaboration skills. 

As a business analyst, you will deal with various people at different positions with distinct personalities. This question is crucial as it conveys whether you can successfully navigate interactions with different stakeholders or not.

Dealing with difficult stakeholders is a significant responsibility for any business analyst. Use the STAR method to explain the situation you were dealing with, what your task or role was in the case. Outline the action you took to resolve the problem. Finally, describe the result & learnings of your actions.

29. How can you manage the post-implementation and pre-implementation problems of a project?

You can answer this by briefly explaining both the problems. The problems that declare their presence before the project implementation are called pre-implementation problems. The difficulties arising after the project implementation are called post-implementation problems, and most of the concerns fall in this category. 

After that, you can explain that a business analyst cannot overcome all these problems but can limit them up to the maximum extent within a minimum time frame.

30. During the development of a system, how do you manage frequently changing customers' requirements?

It is one of the most frequently asked business analytic interview questions. The first task of a business analyst is to draft a document stating the number of changes that are allowed, and after a certain point, no amendments will be accepted. It is vital to get this document signed by the user.

In case the change required is accepted, make sure to note down all the changes and find out their overall impact on the project. Calculate the timeline, cost, and resources needed for this change.

31. What is Scope creep and how can you avoid Scope creep?

Scope creep is a problem that can occur during the development of a project, when the scope of the project gradually expands beyond its original parameters. This can happen for a variety of reasons, such as changes in the requirements or objectives of the project, or simply due to poor planning.

Avoiding scope creep can be difficult, but it is essential in order to keep a project on track. One way to do this is to have a clear and concise definition of the project's scope from the outset, and to make sure that all stakeholders agree on this definition. It is also important to have a well-defined change management process in place, so that any changes to the scope are carefully considered and approved by all relevant parties. Finally, regular communication with all stakeholders can help to ensure that everyone is aware of the project's current parameters and objectives.

If you are experiencing scope creep in your own project, it is important to take action to address the problem as soon as possible. Allowing the scope to continue to expand unchecked can lead to significant delays and cost overruns, and can ultimately jeopardize the success of the project.

32. What is requirement prioritization? What are the different techniques used for it?

Prioritizing requirements is a critical part of the requirements gathering process. It helps ensure that the most important requirements are addressed first, and that resources are used efficiently. There are a variety of techniques that can be used to prioritize requirements, including cost-benefit analysis, value-based prioritization, and stakeholder analysis.

Cost-benefit analysis is a technique that assesses the costs and benefits of each requirement. This can be used to identify which requirements are most important in terms of cost-effectiveness. Value-based prioritization is a technique that assesses the value of each requirement, based on factors such as how important the requirement is to the user, how likely it is to be used, and how complex it is to implement. Stakeholder analysis is a technique that assesses the importance of each requirement based on who will be affected by it. This can help identify which requirements are most important to the stakeholders involved.

No matter which technique is used, it is important to involve all stakeholders in the decision-making process. This will help ensure that the requirements that are prioritized are those that are most important to the project.

33. What is the fundamental difference between a requirement and need in a business analysis perspective?

There is a fundamental difference between requirements and needs in a business analysis perspective. Requirements are specific, measurable, attainable, relevant, and time-bound statements that describe what the business wants to achieve. On the other hand, needs are broader statements that describe the general problem or opportunity that the business is trying to address. In order to create effective requirements, the business analyst must understand the needs of the business and then translate them into specific, measurable, attainable, relevant, and time-bound requirements.

34. What are non-functional requirements and how do you capture them?

Non-functional requirements are those that specify conditions that a system must meet in order to be successful. They are often contrasted with functional requirements, which detail the specific behaviors that a system must exhibit.

There are many different types of non-functional requirements, but some common ones include performance, security, scalability, and usability. Capturing these requirements can be challenging, as they are often less well-defined than functional requirements.

One way to approach this is to think about the different types of users that will be using the system, and what their specific needs are. For example, if you are building a website, you will need to consider the needs of users with different levels of internet access speed, as well as those with different levels of computer literacy.

Another way to capture non-functional requirements is to use scenarios. Scenarios are stories that describe how a system will be used in a real-world setting. They can be useful for uncovering unanticipated requirements, as well as for helping to define the acceptable limits of system performance.

Overall, non-functional requirements are an important part of any system development project. By taking the time to think about the different types of users that will be using the system, and by using scenarios to capture real-world usage, you can ensure that your system meets the needs of all its users.

35. Which documents are used to capture non-functional requirements?

There are a few different types of documents that can be used to capture non-functional requirements. One type of document is called a use case. Use cases can be used to capture information about how a system should work and what its capabilities should be. Another type of document that can be used to capture non-functional requirements is called a business requirements document. This type of document can be used to capture information about the business goals of a system and what functions it should perform. In addition, technical specifications can also be used to capture non-functional requirements. These types of documents can be used to capture information about the technical details of a system and how it should be implemented.

36. What is an activity diagram and what are the important elements of it?

An activity diagram is a graphical representation of the sequence of activities that take place in a system. The main purpose of an activity diagram is to model the flow of control within a system.

There are four important elements that should be included in an activity diagram:

  • Activities: These are the actions that take place within the system.
  • States: These represent the different states that an activity can be in.
  • Transitions: These indicate the order in which the activities take place.
  • Objects: These are the objects that are affected by the activities.

37. What is the difference between exception flow and alternate flow?

The main difference between exception flow and alternate flow is that exception flow deals with unexpected events that occur during the execution of a program, while alternate flow deals with expected events.

Exception flow is used to handle errors or unexpected conditions that may occur during the execution of a program. Alternate flow is used to specify the order in which different parts of a program are executed.

Exception flow is typically used to deal with errors, such as unexpected input from a user or an unexpected condition that occurs during the execution of a program. Alternate flow is typically used to specify the order in which different parts of a program are executed. For example, alternate flow can be used to specify that one part of a program is executed if a condition is true, and another part of the program is executed if the condition is false.

Exception flow and alternate flow are both important concepts in programming . Exception flow is used to deal with unexpected events that may occur during the execution of a program, while alternate flow is used to specify the order in which  different parts of a program are executed.

38. Do you think a business analyst should be involved in testing?

There is no one-size-fits-all answer to this question, as the level of involvement of business analysts in testing will vary depending on the specific project and organization. However, in general, it is beneficial for business analysts to be involved in testing, as they can provide valuable insights into the requirements and help ensure that the final product meets the needs of the business.

39. What does INVEST stand for?

INVEST stands for Independent, Negotiable, Valuable, Estimable, Sized-Appropriately, Testable.


A user story should be self-contained and not depend on other user stories. otherwise, it risks becoming a blocker for other features.

User stories should also be independent from one another so that they can be prioritized and worked on independently.

User stories should be written in a way that leaves room for negotiation. They should not be too specific or too detailed. This allows for flexibility and allows the team to add their own insights during implementation.

A user story should always represent value for the user. It should be something that the user wants or needs.

User stories should be small enough that they can be estimated. If a user story is too big, it should be broken down into smaller user stories.


User stories should be the right size. They should not be too big or too small. The team should have a good understanding of what the user story is and what it entails before starting work on it.

User stories should be testable. This means that they should have Acceptance Criteria that can be used to verify that the user story has been implemented correctly.

40. What is Pareto Analysis?

Pareto analysis is a technique used to identify the most important factors that contribute to a particular problem or goal. It is named after Italian economist Vilfredo Pareto, who developed the concept in the early 20th century.

Pareto analysis can be used in any situation where there are multiple contributing factors to a problem or goal. It is especially useful in business and quality management contexts, where it can help identify the most important areas to focus on in order to achieve the greatest improvement.

To carry out a Pareto analysis, all of the contributing factors must first be identified and then ranked in order of importance. The most important factor is then addressed first, followed by the second most important, and so on.

Pareto analysis is a simple but powerful tool that can help to prioritize efforts and resources for maximum impact. It is also known as the 80/20 rule, due to the common finding that 80 percent of problems are usually caused by 20 percent of the factors. This rule is not always accurate, but it is a good general guideline to keep in mind.

If you are facing a problem with multiple contributing factors, Pareto analysis can help you to identify the most important ones to focus on. It is a simple but powerful tool that can make a big difference in the effectiveness of your efforts.

41. What is BPMN and what are its basic elements?

BPMN, short for Business Process Model and Notation, is a standard graphical notation used to model business processes. BPMN was created to provide a common language that both business users and technical developers could use to document and communicate business processes.

The basic elements of BPMN are:

  • Event:  An occurrence that triggers a process
  • Gateway: A decision point in a process
  • Activity: A task that needs to be performed
  • Data Object: Information that is required or produced by an activity

These elements can be combined to create a visual representation of a business process. BPMN diagrams are typically used to model processes that are repetitive and have well-defined start and end points. However, they can also be used to model more complex processes that are less structured.

BPMN diagrams can be created using a variety of software tools. Some of these tools are designed specifically for creating BPMN diagrams, while others are general-purpose diagramming tools that support BPMN.

BPMN is a powerful tool for modeling business processes. It can be used to document and communicate processes, and to identify potential improvements. When used correctly, BPMN can help organizations to improve their efficiency and effectiveness.

42. What is Kano analysis?

Kano analysis is a quality management tool that helps businesses identify customer needs and preferences. It can be used to improve product development, customer satisfaction, and marketing strategies.

The Kano model was developed in the 1980s by Japanese quality management expert Dr. Noriaki Kano. It consists of five levels of customer needs:

  • Basic needs: These are the essential features that customers expect from a product or service. They are also known as "must-have" or "threshold" requirements.
  • Performance needs: These are the features that improve the product's or service's performance. They are also known as "satisfiers."
  • Excitement needs: These are the features that make the product or service more exciting or appealing to customers. They are also known as "delighters."
  • Reverse needs: These are features that customers do not want and can even be considered negative. They are also known as "dis-satisfiers."
  • Unknown needs: These are features that customers may not even know they want or need until they see them. They are also known as " latent" or "unstated" needs.

The Kano model can be used to assess customer needs at each stage of the product development process, from initial planning to final delivery. It can also be used to evaluate customer satisfaction with existing products and services.

Kano analysis is a powerful tool for businesses of all sizes. It can help them identify customer needs and preferences, improve product development, and create more satisfied customers.

43. What is Benchmarking?

Benchmarking is the process of comparing the performance of a company or individual against others in the same industry. This can be done in terms of specific metrics such as profitability, productivity, or customer satisfaction. Benchmarking can also be used more broadly to compare any aspect of a business's operations.

The main purpose of benchmarking is to identify areas where a company can improve its performance. By understanding how others in the industry are operating, a business can develop strategies to better compete. Benchmarking can also help companies keep track of their own performance over time and ensure that they are making progress towards their goals.

44. How do you decide that as a business analyst you have gathered all the requirements?

There is no definitive answer to this question, as it will vary depending on the specific project and requirements. However, there are some general guidelines that you can follow in order to ensure that you have gathered all the necessary requirements.

To start with, you should always consult with the project stakeholders to get their input on what they feel are the most important requirements for the project. Once you have a good understanding of the stakeholders' needs, you can then begin to compile a list of all the functional and nonfunctional requirements for the project.

It is also important to keep in mind that requirements can change over time, so you will need to periodically review and update your list of requirements as needed. Finally, when you are confident that you have gathered all the requirements, you can then begin to work on creating a project plan and budget.

45. How do you perform requirement gathering?

There are many ways to perform requirement gathering, but some common methods include interviews, focus groups, surveys, and document analysis. When choosing a method, it is important to consider the type of information you need as well as the resources available to you.

Interviews are often used to gather requirements because they provide an opportunity for in-depth, open-ended conversation. They can be conducted in person or over the phone, and they work well when you need to gather detailed information about someone's thoughts or experiences. However, interviews can be time-consuming and expensive if you need to speak with a large number of people.

Focus groups are similar to interviews in that they provide an opportunity for open-ended discussion. However, they involve a small group of people  who are asked to discuss a topic together. This can be a useful method for exploring different perspectives on an issue and for generating new ideas.

Surveys can be used to gather quantitative data about people's opinions, experiences, or knowledge. They can be administered in person, by mail, or online, and they are often used when researchers need to collect data from a large number of people.

Document analysis is a method of gathering information by analyzing existing documents. This can be useful for understanding historical trends or for collecting data that is not easily measured through other methods. When using this method, it is important to consider the bias that may be present in the documents you are analyzing.

46. Why is it necessary for a business analyst to get involved during the implementation of requirements?

There are many benefits to having a business analyst involved during the implementation of requirements. First, the business analyst can ensure that the requirements are clear and unambiguous, which can help avoid misunderstandings and errors during implementation. Second, the business analyst can work with the development team to ensure that the requirements are properly implemented and meet the needs of the business. Third, the business analyst can provide valuable feedback to the development team during testing and validation, which can help improve the quality of the final product. Finally, the business analyst can help document the requirements and the implementation process, which can be useful for future reference.

47. What is the difference between Business analysis and Business Analytics?

There are a few key differences between business analysis and business analytics. Business analysts tend to focus on identifying opportunities and improving processes, while business analytics professionals focus on analyzing data to support decision-making. Additionally, business analysts typically have more of a business-focused background, while business analytics professionals often have stronger technical skills. Finally, business analysts may work more closely with business stakeholders to understand their needs, while business analytics professionals may spend more time working with data.

Despite these differences, the two disciplines are often complementary, and many organizations find that they need both business analysts and business analytics professionals to function effectively. By combining the skills of these two groups, organizations can gain a better understanding of their data and use it to improve their business operations.

48. What is process design?

Process design is the creation of a process to achieve specific objectives. It involves the specifying of operating conditions, raw materials, equipment, and other aspects of the process. Process design also includes the determination of desired output levels, process flow diagrams, and other process characteristics.

49. What is the Agile Manifesto?

The Agile Manifesto is a set of principles for software development that emphasizes individuals and interactions over processes and tools, customer collaboration over contract negotiation, and responding to change over following a plan.

50. What are the essential qualities of an Agile BA?

An Agile Business Analyst is someone who understands the agile methodology and is able to help a team work within that framework. They need to be able to communicate effectively, be organized, and have a strong attention to detail. They should also be able to work well under pressure and be able to adapt to changes quickly.

51. When should you use the Waterfall model instead of Scrum?

There is no one-size-fits-all answer to this question, as the decision of which software development methodology to use depends on several factors specific to each project. However, in general, the Waterfall model may be more appropriate for projects with well-defined requirements and deliverables, while Scrum may be more suitable for projects that are more flexible and evolving. Ultimately, the decision of which methodology to use should be based on a careful evaluation of the specific needs of each project.

52. What are the four key phases of business development?

  • The first phase of business development is known as the ideation stage. This is when an entrepreneur has an idea for a new business venture. They will need to research the feasibility of their idea and develop a plan to bring it to market.
  • The second phase of business development is the implementation stage. This is when the entrepreneur begins to execute their business plan. They will need to secure funding, build a team, and develop their product or service.
  • The third phase of business development is the growth stage. This is when the business starts to gain traction and grow. The entrepreneur will need to focus on scaling their operations and expanding their customer base.
  • The fourth and final phase of business development is the exit stage. This is when the entrepreneur decides to sell their business or take it public. They will need to plan for this eventuality and ensure that their business is in a position to be successful.

53. What do you know about Kanban?

Kanban is a popular system for managing workflows, and has been used in a variety of businesses and industries. It is based on the Japanese word for "sign" or "card," and was originally developed as a way to manage assembly line production in manufacturing.

Kanban has since been adapted for use in other industries, and has been found to be helpful in managing workflows in a variety of businesses. In recent years, it has become popular in the software development industry as a way to manage agile software development.

54. Mention some of the most important Agile metrics.

There are a number of metrics that can be used to measure the success of an Agile software development project. These include:

This measures the amount of work that is completed in a given time period. It is a good indicator of productivity and can be used to predict how much work can be completed in future sprints.

This measures the time from when a user story is created to when it is delivered. It can be used to identify bottlenecks in the development process and to improve the flow of work.

This measures the time from when work on a user story starts to when it is completed. It can be used to identify areas where the development process is taking too long and needs to be streamlined.

Defect Density

This measures the number of defects per unit of code. It is a good indicator of the quality of the code and can be used to identify areas where the quality needs to be improved.

Test Coverage

This measures the percentage of code that is covered by tests. It is a good indicator of the quality of the tests and can be used to identify areas where the test coverage needs to be improved.

These are just some of the most important agile metrics. There are many other metrics that can be used to measure the success of an agile project. The important thing is to choose the right metrics for your project and to use them to drive improvements.

55. Explain the term ‘increment'?

The term ‘increment’ is used to describe the process of adding a value to a variable. For example, if we have a variable called ‘counter’, and we want to add one to it, we would say that we are incrementing the counter by one. Similarly, if we have a variable called ‘total’, and we want to add 10 to it, we would say that we are incrementing the total by 10.

56. What are the different types of Agile methodologies?

There are several types of Agile methodologies, each with its own unique approach to software development. The most popular Agile frameworks include Scrum, Kanban, and Extreme Programming (XP).

Also Read: Benefits of Agile Methodology

57. Is there any difference between incremental and iterative development?

Both incremental and iterative development are software development processes that focus on delivering small, frequent updates rather than large, infrequent ones. The main difference between the two approaches is that incremental development delivers functionality in small, discrete chunks, while iterative development focuses on delivering larger pieces of functionality incrementally. 

58. Difference between extreme programming and scrum?

There are a few key differences between extreme programming (XP) and scrum. The most notable difference is that XP focuses on code quality and customer satisfaction, while scrum emphasizes delivering working software quickly. Additionally, XP requires developers to work in close collaboration with customers, while scrum relies on input from a product owner. Finally, XP uses a "test-first" approach to development, while scrum employs an "iterative and incremental" approach. Despite these differences, both XP and scrum are agile software development frameworks that emphasize collaboration, customer involvement, and iterative development.

Business Analyst Interview Questions and Answers – How to Really Sell Your BA Skills

If you are preparing for your first business analyst job interview or if it’s been awhile since you’ve interviewed, you are probably wondering what to expect. Interviewing for a business analyst job is very different than interviewing for a more technical or domain-focused role.

In particular, what’s different is how you position your skills to a potential employer. I’ve been on both sides of the business analyst job interview process multiple times – I’ve hired several BAs and, while I was contracting, I interviewed for several BA positions.

In this video, I share my insider tips on how to prove or show your business analysis skills in an interview.

For those who like to read instead of watch, here’s the full text of the video:

Today we’re going to talk about job interviews, specifically, how do you sell your skills in a business analyst job interview?

Let’s jump right in.

Two Types of BA Job Interview Questions

In my experience, there are two kinds of questions where employers are looking to understand your skills and the competencies that you bring to the table. The first is a knowledge-based question, which would be along the lines of,

“Can you tell me what a business process is?” “Can you tell me what a use case is?”

These are general questions about a specific skill that feels like they’re asking you to tell them what you know about that skill.

The second is a behavioral interview question, which is, “Tell me about a time when…”

“Tell me about a time when you used a use case.” “Tell me about a time when you analyzed a business process.”

This is a different kind of question because they’re asking for you to talk about your experience.

Now, here’s the catch. I really think that for both kinds of questions, what employers are really looking for or what an individual is really looking for is to understand that you can do the things that they need you to do to be successful in that job role. That means, they want to hear about your experience.

You could simply answer,

“Oh, a business process. That’s a step-by-step workflow of how a business user completes a task.”

Great. You could have learned that out of a textbook. If you answer the question, “Can you tell me what a business process is?” with a textbook answer, no matter how correct it is, it’s not going to feel nearly so awesome and validating and confidence-building as,

“You know, a business process, that’s a step-by-step workflow of how a business user completes a process or adds value to the organization. One time I had this project where we had to analyze five different business processes and they were all related and it was in the accounting department. We looked at their accounts receivable processes and we discovered all these issues about why we weren’t receiving as much money as we should be.”

And now you start talking about how you  improved the process and engaged stakeholders in the process and analyzed the process. Who is going to stand apart? The person who has the perfect textbook answer? Which is why nobody else can give you an answer to a job interview question because that textbook answer isn’t what people are looking for.

They ’re going to be like, what I really want to know is that this person can do business process analysis or do use case modeling or do whatever it is that I’m asking them about. That experience, that sharing of a specific example is going to build that rapport, is going to build that confidence that they have in you and your skill set.

Be thinking about how you can share those examples in an interview.

This Also Works for Questions about “Soft” Skills

This approach works for all kinds of topics too. Another typical interview question that a business analyst might face is,

“Tell me how you handle difficult stakeholders.” or “What do you do if nobody shows up to your meeting?”

Again, you can give that theoretical hypothetical answer like,

“Oh, if I have a difficult stakeholder, I’m going to try to build a relationship. I’m going to work with them 1:1.”

That’s all good stuff, all things that you want to be saying in a certain way, but what’s going to be more powerful is,

“There’s this project where I had this really challenging stakeholder and I didn’t think I was going to be able to break through it. Here are some of the reasons that they were challenging to work with. Here are some of the problems that caused and the requirements process. Here’s what I did and here is what our end result is.”

Just that flavor of how that shifts the conversation from what you hypothetically would do, to what you’ve actually done .

As much as possible in a job interview, I think, especially if you’re having issues getting to the second interview or getting the job offer once you get a second interview, be thinking about how can you share those experiences and how can you demonstrate that you have those skills that the employer is looking for. This is going to make a difference in terms of how they come away from the interview and their experience with you as a potential candidate.

One Last Tip – Do Your Research

I knew there was one more important thing I wanted to cover, and that is how to figure out what job interview questions they might ask.

You want to start with a job description . Most people do this, but there have been times when I’ve heard people say, “Yeah, it was the job posting, but I just didn’t think they’d ask about it.” No, if it’s in the job posting, make sure you know all the terms in the job posting, what they mean, what the alternative variations of those terms are. Do the research on the terminology so that you can say, “Yes.”

Adam Haesler has a great case study  about saying “Yes” in a job interview instead of, “No, I don’t know how to do that.” How can I say yes? And to what degree can I say yes? That starts with knowing the terminology so when they ask you a question and use that term, you can say, “Yes.”

For example: “Yes, I have done a wireframe . We actually call them prototypes, and here is the kind of user interface model I created.”

You want to say yes, and that requires knowing the terminology.

The second place, though, to get the terminology is in the LinkedIn descriptions or the LinkedIn profiles of other business analysts, or whoever has that job title that you’re interviewing for, inside their LinkedIn profiles, what words do they use to talk about their responsibilities, and what they contribute to the organization?

It’s another area to research. Not all the time do job postings have the most current information. Sometimes they’re old. Sometimes they’re created by somebody that’s not actually doing the hiring. There are a lot of reasons they can have outdated information. LinkedIn would just be another resource. Not, necessarily, a more definitive resource, because sometimes people don’t always update their profiles either, but another resource to understand the terminology that is being used by the business analyst inside that organization. Just a quick insider tip for you.

I do have an interview prep guide , completely free. If you want to go through our process at Bridging the Gap of how to prepare for a job interview, be sure to download the interview prep guide. It will walk you step-by-step through how to put together your stories, how to think about the research that you do, what steps you need to go through to walk into that interview with confidence and ability to handle the unexpected.

That’s the final piece I’ll tell you. No matter how much preparation you do, no matter how well researched you are, you’re going to have unexpected things come up in a business analyst job interview, and you’re going to have unexpected things come up in a business analyst job role. Showing that you can handle that with grace and ease and confidence is part of the battle of being successful in a business analyst job interview.

Top 10 Business Intelligence Case Studies and Solutions

Top 10 Business Intelligence Case Studies and Solutions

Business intelligence case studies are generally scenario-based questions that ask you to work through a solution to a proposed business problem.

For example, in a business intelligence case interview, you might be asked: How would you de-duplicate product listings that don’t have the same title, SKU, or description?

Your job is to ask the interviewer for more information, make assumptions about the case, propose a solution, and finally, consider the trade-offs of your solution. For business intelligence engineering roles, business case studies tend to fall into two broad categories:

Analytics - Analytics questions test your understanding of metrics and how they relate to business goals. Your job is to ask the interviewer for more information, make assumptions about the case, propose a solution, and finally, consider the trade-offs of your solution.

Database Design - Database/ technology questions ask you to design or discuss a tech solution to a given business problem.

Generally, business intelligence case studies are the most difficult part of business intelligence interviews, but using frameworks and understanding how they are graded can help you to prepare for your next BI case study interview.

What Does a Business Intelligence Engineer Do?


Business intelligence (BI) engineers are technology specialists who ensure that analysts and data scientists have access to the right data and technologies. A key responsibility is ensuring that the company’s data is organized and accessible. BI engineer case interviews mirror the type of work that candidates will perform on the job.

Specific tasks business intelligence engineers do include:

Creating reports, developing dashboards, and implementing analytics applications such as DataMiner or Tableau Desktop

Designing, developing, and maintaining data warehouses to store large volumes of structured, semi-structured, and unstructured data

Selecting hardware, software, and database management systems for data warehousing projects in line with organizational goals

Training and onboarding users to use business intelligence software

What Is a Business Intelligence Case Study?

Case studies are a common business intelligence interview question that present the interviewee with a specific business problem. The interviewee must then talk the interviewer through a potential solution for that problem.

Most business intelligence case studies cover designing dashboards or creating databases to function for business needs. Therefore, most problems are general business case studies or technical SQL case studies, and the interviewee must solve a problem relating to how data is being presented or stored.

A typical framework for solving business intelligence case questions includes four steps:

1. Clarify - Your first step should be to gather more information from the interviewer. Case studies tend to be vague and lack information. You’re responsible for digging in and finding out exactly what the question is asking.

2. Make Assumptions - Start forming a hypothesis and talk through your reasoning. Your goal should be to land on one hypothesis/solution for the problem, which you will analyze further.

3. Propose a Solution - State your solution, and talk the interviewer through your processes for building the solution.

4. Conduct Further Analysis - For analytics case studies, you’ll want to narrow your investigation to one key metric and support your hypothesis with data. For database design case studies, you’ll walk the interviewer through the schema for a database.

How Are Business Intelligence Case Interviews Graded?


There is not a set grading rubric for business intelligence case studies, as it’s often at the discretion of the interviewer. However, there are some areas you should focus on that will make your response stronger:

Curiosity- Clarifying questions helps you narrow your response. An Amazon business intelligence engineer told us: “If you don’t ask questions, the interviewer could fail you, because they wanted to give you some information to steer the discussion down a particular path.”

Ability to take direction - Our source said: “The interviewer decides where the candidate needs to end up in their solution.” Therefore, it’s important to take hints and coaching during the interview.

Thoroughness - Case questions assess the depth of your problem-solving approach. You can show this by asking clarifying questions, providing multiple data points for analysis, and making assumptions (and checking that those assumptions are correct).

Ability to adapt - Inevitably, something unexpected will come up in a case study question, like your preferred method isn’t feasible, and you will have to adapt. Take the cues the interviewer provides, and always be willing to change courses if needed.

Communication - BI cases assess your ability to summarize your solution and clearly explain your thought processes and assumptions. One tip: Ask the interviewer if they have any questions throughout your response. This can help you clarify your answer at the moment.

There’s no right or wrong answer to case study questions. Rather, candidates are graded on the quality of their responses. Using a framework will help you structure your response more clearly.

Business Intelligence Case Study: Mock Interview

Let’s take a look at an in-depth mock interview solution to a business intelligence case question asked at Amazon:

1. You want to de-duplicate products from multiple sellers in a large eCommerce database. How would you approach this?

More context. Products are listed under different seller names. So for the same product, we might see many variations, e.g., iPhone X and Apple iPhone 10. However, let’s say this example shows up for a lot of different products in various categories.

See a full mock interview solution to this question on YouTube .

Example Solution:

Here’s an edited solution from the mock interview:

Interviewee: “If it’s an established e-commerce company, I would assume that they would have some kind of an ID for every product in their inventory. So something like an SKU or an ID. And if it’s Amazon, then that’s pretty unique, and you know that even if the description is different under different sellers, I would assume that they would have the same SKU.”

“So if you just look at the list of all the SKUs and different sellers and then do a distinct GROUP BY on SKU across all sellers, you’ll find out which SKUs are replicated. And then, once you have that, you can go to the business team saying what you want to do with them.”

Follow-Up Question 1: Let’s say you don’t have an SKU. People create their product titles, along with an image and descriptions.

How would we then do the mapping to the SKU, or would you think of a different approach towards solving the problem?

Identifying Similar Images

“If we have images for these products that we think may be duplicated, we could try to use an algorithm to identify similar images. Then once you have that list of similar images, you look at the descriptions and build a string similarity algorithm that outputs which descriptions sound similar or are close to each other. Now you would have at least two data points that you know these two products are similar. Then it’s probably going to be a little bit of manual intervention to identify if they really are similar or not.”

Similar Product Reviews

“The other thing that I can think of is maybe reviews on different products. So imagine that there are two different products just named differently, but both of them are the Apple iPhone 10. You would assume that the reviews are pretty much talking about a phone and that it’s manufactured by Apple. They probably have the same kinds of experiences and reviews, so you could see if the reviews are very similar to each other, and that would give a good indication that the product is probably the same. ”

Follow-Up Question 2: We’re looking at similarities across images, descriptions, and reviews, and we’re getting this score for each one of them. Now how do we go about deciding if we can de-duplicate them or not?

Would we have a human review every single one? Do we do some sort of scaling process? Because let’s say we have to do this for thousands and thousands of products, right? What’s the next step?

“Well, from the beginning, we don’t really know which products are the same or not, so we can’t do a supervised learning method. It needs to be an unsupervised technique that first tries to identify what products are similar to each other. I probably would do a clustering technique based on just descriptions and reviews.”

“We’ll definitely need to do some cleaning and tokenization for the text data to bring it to a structured format. Then we can run a TF IDF on different descriptions and reviews to find out which documents are similar. We’ll get some scores depending on how many documents end up in a particular cluster, and we will definitely have to do a manual step to see if they’re actually the same or not.”

“ I’m unaware of a clustering technique that works on images, but we would probably have to build out features from the image, bring it to a structured format, and then do clustering on top. So we might identify ten different clusters if there are ten items that are duplicated and then look at the clusters’ descriptive statistics to see if the customer in reviews is really talking about a phone, a tablet, or a computer. And then try to go about in a manual investigation from that point.”

Follow-Up Question 3: Let’s say we do that. We’re going through these clusters, and we find that the algorithm clustered just phones together instead of doing a specific enough cluster for the same product. Or maybe we’re getting thousands of different clusters that may or may not be duplicated.

Is there any way that we can optimize our manual intervention or scale this problem out so that we use the least amount of manual oversight while also figuring out a way to deduplicate efficiently?

“I guess it would depend on the features that we actually extract, as the more granular the features in our dataset, the better the clusters could be. If we are creating clusters just on the type of device, then you’re right. I think all phones and all computers will just end up together.”

“But if we are given that these are also duplicate listings, we would definitely want to look at more information in the listing itself; like the price of the product, the different types of colors that are available, and then the features in iPhones and Androids that are similar to each other. The features need to be as close to the product itself so that our clusters are more identifiable amongst each other and not as generic as phones and computers.”

“Finally, we could look at customers to see purchasing behavior. iPhones typically tend to sell out as soon as they are launched, so we can try to use the information around when a particular product was launched and then look at the purchase pattern during that time and then try to integrate these features into the dataset.”

Mock Interview Feedback

The example response provided some solid jumping-off points to solve the problem. However, there were missing factors that could have made the response stronger:

Consider the Scope

The response focused primarily on the example provided in the problem statement, e.g., iPhone X vs. Apple iPhone 10. However, in business case studies, it’s important to consider the broader context and incorporate that into your answer. In this case, considering a wider variety of products would have made the response stronger.

Having Multiple Data Points

In the example, there was just one type of product proposed. Having more data points to explain these concepts would have made the response more thorough and would have provided more examples to illustrate the proposed solution.

Considering Limitations

This particular response would have benefited from considering trade-offs to the proposed solution. In particular, the response didn’t address limitations like threshold error rates and automation. How accurate can we get with an automated word-matching solution, and would we be satisfied with the threshold?

Ultimately, the response could have benefited from a dialogue about implementation and business impact, as well as the technical details.

Additional BI Case Study Questions

Practice for the business intelligence interview with these sample database design and analytics case study questions:

2. Your company is launching a software product. Would you hire a customer success manager or use a free trial to grow the product?

The hypothesis you want to test is: Does a free trial result in cheaper engagement and acquisition costs, compared to using a CS manager?

Since this is a business intelligence role, you’ll want to frame the question in terms of metrics. Some of the metrics to consider include:

  • Costs of hiring the CSM (continuous) vs cost of free trial implementation (fixed)
  • Conversion rate from free to paid
  • Total revenue gained
  • Future product value

Each one of these metrics can be segmented additionally into new vs existing users. And if we apply weighting to each of these metrics we can ultimately come up with an equation that can maximize our goals.

3. What do you think are the most important metrics for WhatsApp?

An easy BI case study question like this assesses your data sense and the depth of your analytics knowledge. You might start with a clarifying question: Are we interested in revenue statistics (e.g. WhatsApp for Business) or more general user metrics?

For more general user engagement metrics, you could propose something like:

  • Daily active users (how would you define this?)
  • Average time spent on the platform by DAU
  • Average number of messages sent per user
  • Year-over-year or month-over-month increase in the average number of messages by users in different percentiles
  • Churn rate and retention curve

As you propose metrics, be sure to tie them back to the business. Answer this question: Why does this metric matter to WhatsApp?

4. What metrics would you look at to determine the demand for rides on a ride-sharing app? What metrics would tell you there is high demand and low supply?

First, define some of the metrics. Demand would be the number of ride requests, while supply would be the number of available drivers. How would you further analyze ride requests to measure demand?

See a full mock interview solution for this question on YouTube:

5. In an insurance database, the marriage attribute column is marked TRUE for all customers. How would you debug what happened?

Follow-up question: What data would you look into and how would you find out who is actually married and who is not?

With this question, you’d want to start with some clarifying questions like:

  • What’s the table structure like?
  • How long has the bug existed?
  • Where is the insurance company located?

One first step would be to look at what went wrong. You could look at UPDATE and INSERT queries to identify what might have caused the problem initially.

Next, you might look for an easy solution. Are there dimensions or columns related to marriage? If there was a column, for example, this would provide insights into whether a client is married or not. You could also look to see if reverting the data would show the correct marriage status before the bug existed.

A more complex approach might be to GROUP clients by the last name and then see if entries with the same last name share an address, insurance plan ID, etc.

6. You work for a SAAS business. To catch up to end-of-quarter revenue goals, would you send an email blast to your entire customer list?

Broadly speaking, sending a mass email blast to a list of customers is generally not a good idea, especially when the objective of the email is to increase sales.

A better solution is to segment the audience and personalize the messaging by the audience. For example, if a customer was about to reach their licensing limit, we could send a personalized offer to add more licenses, while a win-back campaign could be used for recently churned users.

7. You work for a 14-month-old SAAS company. You’re asked to calculate the average customer lifetime value. How would you do it?

More context: We know that the product costs $100, an average 10% monthly churn, and the average customer sticks around for 3.5 months.

Average lifetime value is defined by the prediction of the net revenue attributed to the entire future relationship with all customers averaged. Given that we don’t know the future net revenue, we can estimate it by taking the total amount of revenue generated divided by the total number of customers acquired over the same period of time.

However, there’s a catch: it’s only a 14-month-old company. As a result, the average customer length is biased , because the company hasn’t existed long enough to correctly measure a sample average that is indicative of the mean.

How would you calculate this? Try to find the expected value of the customer at each month as a multiplier of retention times the product cost.

Capital One Case Interview (Questions, Process, Prep)

Capital One case interview

Today we're going to cover everything you need to prepare for your Capital One case interview.

If you're a business analyst, senior data analyst or strategy analyst, and you're not used to case interviews, they can be challenging. That's why we've put together the ultimate guide to the Capital One analyst interview to maximise your chances of success.

Here's an overview of what we'll cover:

  • Assessment tests
  • Case interviews
  • Product questions
  • Behavioural questions
  • Preparation tips

NB: If you're a software engineer interviewing at Capital One, check out our engineering interview guides .

1. Capital One: doing things differently

Capital One is unique. As of the time of this article, it's the 13th largest bank ($450bn in assets)  in the United States, behind firms like  Goldman Sachs , JP Morgan , and Morgan Stanley , despite being founded as a single-business  bank in 1994. The business was initially only focused on credit cards but now include the following 3 verticals:

  • Credit Cards
  • Consumer Banking
  • Commercial Banking

The company's success has been driven largely by its clever use of data . They've developed sophisticated strategies for identifying and directly marketing to profitable customers. This has created a competitive advantage vs. traditional banks, which have historically focused on broad (rather than targeted) marketing.

Capital One also has their own  strategy group , which essentially serves as an internal consulting firm.

Although Capital One is a top player in the banking industry, their unusual history and technology focus, has created a unique culture. It has more of a "tech firm" feel, than you'd expect from a giant financial institution. Another notable area where Capital One is different from their peers, is in their interview process.

2. Capital One interview process

The type of work (and the nature of the interview) you can expect at Capital One varies across group and role. They hire for roles ranging from call center reps, to software engineers and business analysts.

This guide is primarily written for business analyst candidates, but most of what we say here is applicable for anyone with a case interview at Capital One, including senior data anlaysts and strategy analysts.

The application process includes 4 main stages:

  • Resume & cover letter submission
  • Pre-interview online assessment tests
  • First-round interview

Power Day of 3-5 interviews

Let's take a closer look at each step in the Capital One interview process.

2.1 Resume & cover letter submission

First, recruiters will look at your resume and assess if your experience matches the open position. This is the most competitive step in the process—we’ve found that 90% of candidates don’t make it past this stage.

You can use  this free resume guide  and this  free cover letter guide  to help tailor your application to the position you’re targeting. 

And if you’re looking for expert feedback, you can also get input from our  team of  expert recruiters , who will  cover what achievements to focus on (or ignore), how to get more impact from your bullet points, and more.

2.2 Capital One online assessment tests

After the initial application, you'll face the   online assessment tests.

For the business analyst position, the BA quantitative assessment usually consists of 11 questions that aim to assess basic analytical skills. You'll be given a data set and you'll need to use a spreadsheet to solve mathematical and analytical problems.

Example Capital One online assessment question

  • Ali and Sophie are budding musicians who have been playing Thursday night shows at a local live music venue. The venue told them that over the course of the last four weeks, they’ve had 900 tickets sold for their shows. They are curious to see how many people are repeat fans, coming to more than one show. The venue’s recent customer survey says that 60% of fans have come once, 30% have come twice, 6% have come three times, and 4% have come four times. How many unique people have seen an Ali and Sophie show during this time period?

2.3 First round mini case interview

If you pass the online assessment, you make it to the first round 'mini case interview', which will be conducted via phone or video call. Be ready to hit the ground running in this interview, don't expect much "getting to know you" discussion because they usually get straight to the case. This interview will normally last 30 minutes.

2.4 Final round Power Day

The final round, often referred to as a "Power Day" or a "Super Day", is  a series of 3-5 back-to-back interviews .

For the role of business analyst, you can expect two case interviews and one product interview, with behavioral questions thrown in at the start of each interview.

If you're interviewing for a more technical role, such as senior data analyst, you will face a technical interview such as coding or a data challenge, one case interview and one behavioral interview.

Now you know the interview process, let's go deeper into what questions you can expect to face.

3. Capital One interview questions

In this section we'll take a look at the type of questions you can expect to face in your Capital One interview. We'll start with the most important, and the most challenging: case interview questions.

3.1 Capital one case interviews

Case interviews are the most important part of the Capital One interview process. The company has published a video tutorial, which shows the style of their case interviews.

We've embedded it for your reference below. It's a great resource, but it's pretty long (about 20 minutes), so we've also summarised the key take-aways and added some additional commentary below.

Capital One case interviews include 3 sections:

  • Business situation and framework
  • Quantitative question
  • Recommendation

Each section of the case interview has particular things you'll need to prepare for. Let's look at each one in-depth.

A. Business situation and framework

The first several minutes of the interview will cover the business scenario and case framework. This typically begins with the recruiter providing a brief statement about the business or industry where you'll focus for the case. In the sample case (in the video), you're the CEO of Ice Cream Corporation. 

Typically, the recruiter will end their opening statement with a broad question. For example: "What are the key factors you would consider when developing a strategy to grow profits for Ice Cream Corporation?" For this stage of the interview, you should have two objectives.

First, you should ask clarification questions to make sure that you understand the situation correctly. For instance, in the video above the first candidate asks exactly what role the CEO has with regards to "pricing" and to "sales". Many candidates skip that initial step, but it's actually essential because it will help you put together a more relevant framework.

Second, once you fully understand the situation and question the interviewer is asking you, you should put a simple case framework together to answer the interviewer's question. The objective of this framework is to identify and communicate key areas that you will consider to answer the interviewer's main question. For instance, the candidates in the video mention areas including pricing, number of markets, number of competitors, their size, etc.

If you're familiar with the different types of case interviews, you'll notice that Capital One uses the interviewer-led approach. This is similar to the method used by McKinsey in their application process .

That said, we still recommend that you try and drive the case forward yourself to a certain extent, by communicating the implications of your answer with the interviewer. This will show them that you're able to think a few steps ahead and take an active approach to problem-solving.

B. Quantitative question

The second stage of the interview is heavily focused on maths skills. The recruiter will provide you with some data, and ask you to perform calculations.

In the sample case, you're asked to calculate total monthly profit for Ice Cream Corporation, given the following data:

  • Price per carton = $5
  • Cost per carton = $1
  • Demand = 100 cartons/month

It's important to ask questions at this stage, as the recruiter may have additional data which they have not yet provided. The video shows a great example of this, when the candidate asks how much of the cost is variable vs. fixed cost. 

  • Variable cost per carton = $1
  • Fixed cost per carton = $0

At this point, the calculation is straight-forward.

  • ($5-$1) X 100 cartons = $400 profit

Make sure you talk through your logic, to show the recruiter your problem-solving skills. This will also help them to steer you back on track, if you've misheard any of the data.

Don't expect all of the calculations in your interview to be this simple. There are 2 additional examples provided in the video, which include elasticity of demand and break even calculations. These require a little extra work, but your approach will be the same:

  • Understand the data provided
  • Ask for more information when necessary
  • Lay out your approach
  • Perform the calculations

In our experience, the best candidates brush up ahead of their interview, so they can   have confidence in their maths skills . If you do the same, this will give you a polished reaction during interviews, which recruiters will notice. Compared with the case interviews used at consulting firms, the case interviews at Capital One tend to have a greater focus on quantitative questions. So you should expect to spend more time on these types of quant problems during your interview, and less time on other areas, like creative brainstorming.

C. Recommendation

In the final stage of the interview, you'll be expected to make and defend a recommendation. To form your recommendation, draw on the calculations from the previous stage (e.g. the results of the break-even analysis). Consider the numbers, use your intuition, and make a decision . 

For example, this might be your conclusion: "since frozen ice cream is a non-perishable, I think it would be reasonable to expect most of the additional sales from a promotion, to come from stock-up behavior. I'd recommend looking for other opportunities to increase sales."

The specific strategy you suggest, is less important than your logic and ability to defend it . Expect the recruiter to question your approach. For a recommendation like this, they may ask you to explain how you would go about identifying other opportunities.

Additional tips for your Capital One case interview:

  • Don't be surprised if you're given a case from outside the finance industry
  • Take notes on the information provided by the recruiter.
  • Ask for a minute to organize your thoughts when needed.
  • Talk through your thought process, show your work as you do it.
  • If you don't understand a topic, ask the interviewer for clarification.
  • Call out important assumptions.
  • Notice directional cues, as the recruiter may want to steer the conversation.
  • You're usually allowed a calculator, so bring one that's easy to use

3.2 Capital One behavioural and fit interview questions

In addition to case interviews, Capital One also uses behavioural questions/interviews, like most companies do. While you may not get a whole interview devoted specifically to behavioral questions, you can expect to face them at the start of your case and product interviews.

Behavioural interview questions asked at Capital One fall into two main categories:

  • Fit questions. These are generic questions such as “Why financial services?” or “ Why Capital One? ”.
  • Personal Experience Interview (PEI) questions. These are questions such as “Tell me about a time when you lead a team through a difficult situation.” Or “Tell me about a time where you had to manage a team conflict”

We've written extensively about   fit / PEI questions   in another guide. But in summary here are the top 5 fit and PEI questions you should prepare for at Capital One, or other firms.

Top 5 fit questions:

  • Why Capital One?
  • Why financial services?
  • Walk me through your resume
  • Tell me about something not on your resume
  • Tell me about your greatest accomplishment

Top 5 PEI questions. Tell me about a time when ...

  • You failed at work
  • You worked in a team and had to manage a conflict
  • You had a disagreement with a colleague / boss
  • You had to change someone's / a group's mind
  • You led a team through a difficult situation

Capital One is known to favor the STAR method when it comes to answering behavioral questions. So, for your interview, plan to answer behavioural questions using the following format:

  • S - Situation

This approach will help you to answer each question in a clear, and methodical way, which are great qualities to demonstrate when interviewing with Capital One. 

3.2.1 "Why Capital One?" interview question

You're almost guaranteed to be asked this question, so let's dive a bit deeper into how you should answer it. Here are 3 ways to make your answer stand out:

Name-drop: Before the interview, make an effort to meet with or call one or more current employees of the firm. Ask them what it’s like working there, why they chose Capital One and what is unique about it. This will give you good, specific talking points for your answer, and mentioning their names shows the interviewer that you’ve put in effort to get to know the company.

Be specific. Test out your answer by swapping another bank’s name with the one you’ve got in mind. If your answer could also apply to this other bank, then you need to fine tune it.

Keep up with recent activity : Being aware of the latest deals and developments in the department you’re applying to will give you an idea of what kind of projects you’ll get to work on, and whether they sound interesting to you. Bringing them up in the interview will show the interviewer that you’ve done your research and stay up to date on market news.

Example answer: "Why do you want to work at Capital One?"

“I want to work at Capital One for three main reasons. First, I want to work in a very data-driven environment and to have access to a vast amount of data when working strategically. I've been really impressed with Capital One's pioneering use of data and machine learning in the banking sector, which has helped it gain market share across its verticals.

Second, I've also been impressed with Capital One's strategy regarding a banking-as-a-service model and embedded finance. I saw an interview with Richard Fairbank (CEO) talking about how all banks needed to collaborate with fintech apps to provide instantaneous results for customers, rather than working in silos, and I thought he articulated a really strong vision.

And finally, I’ve had a few conversations with Seth White and Tamara Grey, associates in the McLean office, both of whom gave me a great impression of the firm as a whole. Seth in particular encouraged me to apply to the Travel team, as we share a similar educational background, and he was complimentary of the opportunities he’s been given to succeed."

See more details on how to answer the "Why this company?" interview question .

3.3 Product questions

If you're interviewing for a business analyst role, one of your Power Day interviews will be a product interview. Compared to the very quantitative case interviews, the product interview is a lot more qualitative and you'll need to think more creatively.

In almost all the interview reports we've seen over the last year or so, the candidate was asked to improve a product in some way. We recommend you read our article on How to answer product improvement questions to help you structure your response.

Example Capital One product questions from business analyst candidates:

  • Describe 12 uses for an alarm clock
  • How would you redesign an alarm clock?
  • What is the customer base for this product?
  • Describe 10 ways to improve an umbrella
  • How would you improve this water bottle?
  • What's your favorite product and how would you improve it?

4. How do I prepare for a Capital One case interview?

Here's how we recommend you prepare for your Capital One case interview. First, use Capital One case studies to research the company. Second, become really confident at maths. Then, learn a consistent method to approach case interview problems. Fourth, practise a lot and learn from your mistakes. And finally, do mock interviews to hone your case interview technique.

4.1 Use Capital One case study examples for research

Case interviews require no prior knowledge. However, you can bet that overall your interviews at Capital One will go a lot better if you go in having done some research on the company and the wider financial industry.

Capital One shares some case studies on its website, which are well worth looking over. Also take a look at some of the articles on Capital One's insights center . Elsewhere in the media, we liked this piece on how Capital One uses data to get an advantage .

If you're coming from a finance background, you may already have a good knowledge of Capital One's place in the sector. If not, check out Investopedia for a brief summary.

4.2 Become really confident at maths

You don't have to have a perfect GPA or GMAT score to succeed at case interview maths. And in any case, during your Capital One interviews, you will be allowed to use a calculator. That said, it will help if you're confident performing mental maths quickly and accurately.

In order to do this, it’s essential to know the formulas for common metrics, like return on investment or breakeven point. And it’s also helpful to know a few maths shortcuts to help you solve problems more quickly. To learn more about these topics, check out our free guide to case interview maths . 

In our experience, the most successful applicants start their interview preparation by practising maths skills, so make sure you prioritise this step.

4.3 Develop a consistent method to crack cases

One of the biggest challenges of interviewing with Capital One  is solving cases that you’ve never seen before. Each case can be difficult, and you’ll have to perform well across multiple case interviews in order to get an offer.

As a result, it’s critical for you to have a consistent approach for solving cases. Capital One  uses interviewer-led case interviews, which can be broken down into the following types of questions:

  • Framework development
  • Quant question – Data provided
  • Creativity question

If you can crack each type of question (within a case), then you can crack the overall case.

Use this list of example case interviews to practice with. The companies listed here are consulting companies rather than banks, but doesn't matter as case interviews use examples from all sorts of industries, not just the one you're interviewing for.

4.4 Learn from every mistake you make

During case interview preparation, the quality of your preparation is just as important as the quantity of time that you dedicate. It's better to do 20 cases thoughtfully than to rush through 40 cases. 

We recommend that you keep a notebook where you record improvement opportunities and specific things you did well for each case. 

The notebook and self-evaluation will help you to be more strategic (and efficient) with your preparation. It's also a good idea to go back and re-do old cases. For example, after you have done case #20, you could go back to case #1, to make sure you are not repeating the same mistakes.

The minimum preparation time required to succeed in case interviews is probably around 30 hours. However, if you don't prepare thoughtfully, it may take much longer. So take notes, be strategic, and keep practising!

4.5 Do mock interviews

How you solve each case is important, but your interviewers will also be evaluating how you COMMUNICATE your answers. It's important to speak in a structured way that makes it easy to clearly understand your points.

The best way to hone your communication skills is to practise interviewing out loud, and you can do that in three main ways:

  • Interview yourself (out loud)
  • Practise interviewing with friends or family
  • Practise interviewing with ex-interviewers

Practising by yourself is a great way to get started, and can help you get more comfortable with the flow of a case interview. However, this type of practice won’t prepare you for realistic interview conditions. 

After getting some practice on your own, you should find someone who can do a mock interview with you, like a friend or family member.

We’d also recommend that you practise 1-1 with ex-interviewers from top consulting firms . This is the best way to replicate the conditions of a real case interview, and to get feedback from someone who understands the process extremely well.

4 tips to ace your Capital One case interview

You’ve submitted an application for a position with Capital One . Now, it’s time to demonstrate your problem-solving skills through a case interview. 

What is a case interview?

During case interviews, we present you with a hypothetical scenario and objective that is similar to the work you’ll encounter in your role, for example, what factors you’d have to consider to increase the profits of a bus route. They’re an essential part of interviewing, but not all positions require case interviews.

Case interviews are designed to be open conversations, so we want you to take notes, ask questions and think like a business owner when you share your thoughts on the scenario. This is an opportunity to showcase your strategic thinking, communication, creativity and analytical skills.

How to prepare for a case interview

Now that you what to expect for your case interview, here are four tips to help you prepare: 

1. There isn’t one right answer

Your case will involve a bunch of variables—and if you’re thinking broadly—there is naturally going to be more than one final answer. Your answer should take the form of a recommendation about what steps the business owner should take and why. You’ll use the evidence and information from your thought process to back up your recommendation, so make sure to capture your process in an organized way. 

2. Share your thinking and reasoning 

Your interview is ultimately looking to see how you work through a problem, get to your solution and arrive at a final recommendation, so they’re just as interested in how you get to your final answer. Talk to them about your thinking, and be prepared to defend your answer with data.

3. Practice explaining complex concepts

Your interviewer will be looking for your ability to break down approaches in non-technical terms. Think of it like you’re explaining your solution to someone who works in a totally different field. 

4. Avoid talking about your resume

There will be other interviews where you’ll discuss your credentials or accomplishments. For the case interview, you’re gonna want to let your skills and experience shine through your work unpacking the case you’re presented with.  

And remember …

As your case interview approaches, remember to take a deep breath. This is a great opportunity to show your unique perspective. 

P.S. If you're interested in any of our Students & Grads programs, head to the event page to sign up for an interview prep session.
