Develop your maths skills to prepare for consulting firms interviews. This app is created by a former project leader and interviewer at BCG.


Many consulting firms (notably MBBs: McKinsey, BCG, Bain) run case studies during interviews.

These case studies have a quantitative dimension which is tested during the interview.

This application aims at helping you in your preparation for these quantitative elements: mental calculations, interpretation of financial data, interpretation of consultants-like charts (waterfalls, bar charts, ...).

Go through the different levels and arm yourself so that the quantitative part of the case studies becomes much more affordable for you!
