Two cases with intensity varying based on principal, good balance of intense case versus a more laid back one. The behavioral element is pretty straightforward just be yourself my friend.
The process took 4 weeks. I interviewed at Boston Consulting Group (New York, NY)
Interview
Applied online, did a case simulation and was invited for interviews. Had 2 rounds of case interviews in a day. Asked about your motivations, followed by a case, and Q&A
Behavioral interview and bot case in first round. Second round was two 45 min partner interviews. It was a pretty standard management consulting interview process. The bot case was not hard.
