The interview procedure is very similar to the ones at other top tier strategy consultants. Three rounds of interviews, each having two interviews each. Every interviews consists of three parts: the personal interview (CV/experience based), case interview and questions to get a sense of the capability of the candidate to interact. As the rounds progress you will be interviewed by increasingly senior consultants.

Interviewers were really nice, but the process was difficult. Standard level cases and they expected you to take them through multiple business problems. If you practice casing frequently with multiple partners, you should be fine.
