Two back to back case studies over zoom. Different interviews who were very friendly. Overall the process was actually really fun, which is a word I've never used to describe an interview before.
My favorite part, which made me fall in love with Bain, is that one of the interviewers called me to provide feedback after I got the rejection email. After all the companies that waited for months just to send me a generic rejection email, I thought this was really cool. I may not have gotten the internship, but I'm a huge Bain fan now.
