Recruitment took place at Columbia University campus. The first round interview was with one of the CU graduates currently working at BCG HR. It was a very pleasant conversation about my background. The second round interview was in Philadelphia. I had 2 half-hour case case interviews with two different offices-Moscow and Kiev. To my surprise the interview was in Russian. I do speak fluent Russian, however, I got lost in terminology which I learn in English only. The interviewers were very nice and I felt that they liked me and even tried to help me. Nevertheless, I didn't pass this round. I was simply not prepared to do case interviews in Russian. Great experience though, gotta do a better job next time:)
