I applied through university. The process took 2 weeks. I interviewed at Bain & Company (Dallas, TX) in Oct 2015
Interview
For my final round interview I was invited to their offices. They paid for all my expenses and were very accommodating. I had two one hour interviews in which I was asked behavioral questions for 15-20 minutes, did a case for 30 minutes, then had some time to ask questions. The interviewers showed interest in getting to know me and whether or not I'd be a good fit.

Question 1
What was some feedback you received during your last internship?
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.
