Case interview examples (2023): a collection from McKinsey and others

case interview examples from consulting firms such as mckinsey, bcg or bain

Whenever you prepare for case interviews, you have to practice as realistically as possible and mimic the real case study interview at McKinsey , BCG , Bain , and others. One way to do this and make your preparation more effective is to practice real cases provided by the firms you apply to.

It will help you to understand what the differences are across firms, how they structure and approach their cases, what dimensions are important to them, and what solutions they consider to be strong.

Below is a steadily expanding selection of real case interview examples provided by different management consulting firms.

Before wasting your money on case interview collection books that use generic cases, use original cases first. Additionally, use professional case coaches, who interviewed for the top firms , to mimic the real interview experience and get real, actionable feedback to improve.

Please be aware that cases are just one part of a typical consulting interview. It is equally important to prepare for behavioral interview questions .

Practice with experts

Using case interview examples is a key part of your interview preparation, but it isn’t enough.

At some point you’ll want to practise with friends or family who can give some useful feedback. However, if you really want the best possible preparation for your case interview, you'll also want to work with ex-consultants who have experience running interviews at McKinsey, Bain, BCG, etc.

If you know anyone who fits that description, fantastic! But for most of us, it's tough to find the right connections to make this happen. And it might also be difficult to practice multiple hours with that person unless you know them really well.

Here's the good news. We've already made the connections for you. We’ve created a coaching service where you can do mock case interviews 1-on-1 with ex-interviewers from MBB firms . Start scheduling sessions today!
