I applied online. I was invited to interview by phone with a recruiter and advanced to the first round of interviews at their offices in NYC. I spoke with a Manager and a Partner. One behavioral interview and one case interview. Case interviews were new to me, but I did invest in case interview materials and prepared in advance.They even provided a coach. If you are not familiar with the case interview format and you want to work for a top firm, I recommend making the investment well in advance because it is a unique process. I could logically draw the correct conclusions from experience, but did not have enough exposure to the case interview process to present the responses as quickly as the process requires.
