First I had a telephone interview. Pretty standard behavioural questions, the interviewer was nice and gave me an insight into working for the firm, what I could expect etc. Second interview was a case study. It was pretty easy, one A4 side of paper with info, with a few straightforward questions. The interviewers asked me a lot of follow up questions however, until they ran out. Final presentation interview. 10 minute interview (seriously) where I had to give a presentation on anything of my choosing. No follow up questions, was in and out within 10 minutes. Then told I did not have enough experience. I had no problems with the fact that the firm felt I lacked experience, however taking me to the final stage of the process and then telling me something they could have told me at the CV screening process was slightly frustrating.

They took two rounds - one technical (problem solving), and the last round was with HR. Technical round involved general calculations, query optimization in SQL and knowledge on joins. They also asked questions on basic Python.
