The first round interview was a 1:1 interview with an employee. He asked about my resume and there was a short case involved. Because I went to the info session the night before he already knew me so he knew that I knew about the company. I would assume that he would have asked me to tell him my perspective of the company though had I not been to that session.
The second round interview consisted of a one hour lunch, a 30 minute written exam, a 30 minute behavioral interview, a 30 minute leadership interview, another 30 minute interview and a 30 minute case study.
The 1:1 interviews were fairly straightforward. Mostly about projects you worked on or problems you have encountered.
The case study had the same list of options to choose from as the first round but you had to choose something different. I don't remember the question but once again it had to do with basically improving a website. It was different in the way you thought about the question though.
I really enjoyed by time at the interview. The people there were extrememly nice and made me feel comfortable. I think the culture of working there would be fun.
