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.
