The whole interview process was very nice. The first portion included a skype/telephone call and one technical question. After passing this interview they flew out a group of 20 of us from around the country. It was exciting to have such a fun and diverse group from across some of the top colleges and universities. During this process they flew us out the day before the main interviews, had dinner with the VP's, and was a relaxed environment (still business casual attire). The main day we each had 5 interviews consisting of heads of different departments. One interview was a technical question, one was analyzing what we did for our homework, and the other three were all standard interview questions about interests and background.
