1. McKinsey Case Interview Examples
McKinsey Practice Cases
What should I know about McKinsey Case Interviews?
At McKinsey, case interviews often follow the interviewer-led format, where the interviewer asks you multiple questions for you to answer with structured approach.
How do you pass McKinsey Interview? Since the questions can be grouped into predictable types, an efficient approach is to master each question type. However, do that after you’ve mastered the case interview fundamentals!
For a detailed guide on frameworks, check out our article on how you can build your frameworks in case interview.

What you need to know about BCG & Bain Case Interviews?
Unlike McKinsey, BCG and Bain case interviews typically follow the candidate-led format – which is the opposite of interviewer-led, with the candidate driving the case progress by actively breaking down problems in their own way.
The key to acing candidate-led cases is to master the case interview fundamental concepts as well as the frameworks.
Some BCG and Bain offices also utilize written case interviews – you have to go through a pile of data slides, select the most relevant ones to answer a set of interviewer questions, then deliver those answers in a presentation. However, in the recent trend of online interviews due to the pandemic, the huge pile of data slides are optimised for online delivery.

What should I know about Deloitte Case Interviews?
Case interviews at Deloitte also lean towards the candidate-led format like BCG and Bain.
The Deloitte consultant recruitment process also features group case interviews, which not only test analytical skills but also place a great deal on interpersonal handling.
4. Accenture Case Interview Examples
Accenture divides its cases into three types with very cool-sounding names.
- The great unknown
- The back of envelope
- Parade of facts
Here’s the link to the Accenture Case Interview Workbook, with more than a dozen practice cases.
5. Capital One Case Interview Examples
Capital One is a bank-holding company. Nonetheless, this being one of the biggest banks in America, it’s interesting to see how its cases differ from the consulting ones. This is important to provide a contrasting perspective on cases.
Having gone through Capital One’s guide to its cases, we can’t help but notice the less-MECE structure of the sample answers. Additionally, there seems to be a greater focus on the numbers. This is somewhat different than McKinsey Case Interview process.
Nonetheless, having a solid knowledge of the basics of case interviews will not hurt you – if anything, your presentation will be much more in-depth, comprehensive, and understandable!
See Capital One Business Analyst Case Interview for an example case and answers.
