1st round with a phone interview (more like an English test).
2nd round with a synthesis of an article in English, and two (fit + case) interviews. The first one was with a very cold and distant consultant. He made me really uncomfortable which led me to kind of blow the case. The second interviewer was very friendly and the case went well, but damage had already been done...
Rejection only with a standard email saying I have good skills but not the ones Bain is looking for, and no feedback whatsoever. Frankly revolting to have such a poor HR management.
