My name is Georgii. I had two interview days in Big4 Strategy Consulting.
The interview is organised by the following style:
Usually it is you (the candidate) and one or two managers (the interviewees).Managers introduce themselves, and then ask you about your motivation for career in consulting (why do you want to work in strategic consulting? why this company?), also there can be some questions concerning your professional eperience (giving example of projects, difficult situations, important decisions taken by you inyour life).
After that there can be challenges as brain-teasers for you.
And then, you nedd to solve the case of different types (like market-sizing (how many cars in your city, how many smartphones used in your country, etc.), market-entry (should the partucular company enter a new market, launch new product, etc.) and others).
In the conclusion you have an opportunity to ask some specific questions about the company, practices and projects.
Usually the interview is around 40 minutes.
The company gives you feedback in around 2-3 days.
