First I directly talked with their HR and it was smooth process. My first interview with was a partner, he was very easy to talk but the second partner interview was not that much. After second interview they told me I was not successful. I would like to hear more detailed feedback from them.

Three part - all in person! a case study is used at the final stage, where you are interviewed by one of the partners. Emphasis is placed on your thought process rather than actual outcomes
