Senior Consultant

The interview process consisted of the following:

Phone interview with HR, mostly fit and behavioral
2 Phone interviews with Principals, one case interview and one behavioral interview
3 interviews with partners at the office, one on one case interview, presentation case interview with 2 partners and a behavioral interview.

I found the entire process very transparent and pleasant. I had never done case interviews so it was interesting to do them in person. The group case interview was difficult but was a great opportunity for me to flex my analytical muscles and show my ability to present. The interview process was certainly difficult but I think it is easy enough to prepare for it. There are plenty of sample cases on the internet to work with.
