I had a two stage interview about two years ago. Both interviews were with partners, last one being with the Managing Partner. During the first interview I was asked to tell about my education and experience, skills, previous projects etc. as well as to solve a small case. I was also told to do small translations I think from Russian to English. Second interview was with the Managing Partner. Again was asked to tell mainly about education abroad etc. Also was asked some finance related questions. Overall impression was very good and I enjoyed the interview, mainly due to their professional approach.
