Interview
There were two 30 minute interviews. The first one was fit. I don't recall anything being too difficult there, but I remember it ended quite short of the 30 minute mark. The case was extremely hard. There were very confusing charts with weird numbers that I haven't seen before. The case was about introducing a new product and how to analyze the data for it. The interviewer was really nice and wanted me to get it right but I couldn't really get through it. Overall people seemed really nice at the company.

Question 1
Asked to interpret numbers on a very difficult chart. Not simple profit/loss calculations but had concepts nestled inside other concepts.

Interview
Round 1- One case interview and one behavioral interview. Interviews were conducted by managers and partners.
Round 2- One case interview, one behavioral interview, and one written case presentation. The case and behavioral interview was conducted by partners. For the written case I was given a deck of about 30 slides and a problem statement. I had 45 minutes to go through the information and create a power-point presentation that presented my analysis and solutions. I then had a few minutes to present to two managers, followed by a questions.
I interviewed on-campus for round 1 and in Evanston for round 2.

Tell me about a time you worked with a challenging person
I received a phone call to set up a time for an initial interview. While I offered to come in, the procedure dictated that the first interview be conducted over the phone, with a screen sharing program to relay information pertaining to the case (the basis of the interview).

Question 1
The case was pretty straight forward, and my impression was that the interviewer was trying to gain an impression of general math skills. The most awkward part of the interview however, was using the screen share to conduct a case interview.
