First round interview consisted of a standard run through of resume and a pricing case regarding a pharmaceutical drug launch. Second round interview involved 1 math exam (about 15 questions GMAT/SAT difficulty level), interviews with senior consultants, directors, and a partner. Also a fit test during lunch interview. Overall 4 cases. People were all really nice and they really try to help you out in the cases. However, note that the cases were all really quantitative - know your math!

I had 3, 1-hour long interviews with different people. 2 with senior consultants and the last with a director. The first was more heavy on the social aspect, with a 30 min case. The others were much shorter on the behavioural side.
