It was two calls total. It was pretty standard, like other consulting companies. The HR called for the first round of interview, then the project manager called. In the mean time, I interviewed with other consulting firms as well. I choose the other one that works better with my schedule and for networking.

first round, 15 minutes Behavioural question and then 45 minutes for a standard case study. Nothing really out of expectation, but the interviewer asked quite a few follow-up questions regarding the validity of assumptions.
