I got their info from a job fair and gave them my resume. I was contacted a few weeks later with an offer to come interview at their office in Greenville, SC. It was a laid back interview with the Project Manager and the VP and head of HR were in the interview on conference call. It was intimidating at first but everyone is very friendly and just wanted to hear about my background and what I wanted out of the internship. I felt it went pretty well and I accepted an offer from them a week or two later.

Pretty laid-back, had two interviews. The first interview was one-on-one to find out more about my background and what I was looking for. It was basic and informational from both sides. Second interview was with a 3 person panel and was fairly similar to the first with a few easy HR questions.
