I applied through university. The process took 1 week. I interviewed at Bain & Company (Chicago, IL) in Oct 2017
Interview
Two interviewers were truly nice and friendly. They were there to help you go through the whole process. Not so much time for behavioral questions. Tell me about yourself followed by cases.
2 cases for R1. Pretty straightforward cases about revenue optimization opportunities. There was a little bit of market sizing but all data needed was given. No behaviorals asked in round 1 for me.
