It was very laid back. They took me on a tour of the company and asked me "get to know you" questions. There were 3 people sitting in on my interview, and they spent a lot of time explaining their company model and answering my questions.

Very relaxed and completely non-technical. Interviewers wore casual clothes and I was encouraged to do the same in communications before the interview. Interview was basically them talking about the company and the internship briefly and asking questions about experiences in school and personal projects. Interview took place on campus and was fairly short because they were interviewing students back to back all day. Only enough time for one or two questions before they called in the next person.
