I applied online. The process took 5 weeks. I interviewed at Bain & Company (London, England) in Nov 2016
Interview
I completed two interviews with two separate interviewers. Each involved an element of talking about own experiences and then doing a case study. I had to do market sizing of an industry with which I was not very familiar. There was a lot of challenging maths involved - you are likely to be asked to do precise maths, though some of the time estimation maths is sufficient.
Interview questions [1]
Question 1
Talk me through your CV, standard case study (P&L)
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.
