Met the campus recruiters at a meet and greet, followed up and they invited me to an onsite interview. It was with two people and was a fairly easy interview. After that I was invited to Indianapolis for a day of interviews. The night before the interviews all the potential interns had dinner ata local restaurant. The day of the interview we got a tour of the campus and convened in a large room where there were maybe 30 or so of us. I was asked to create a presentation about myself, so I made a powerpoint and printed off slides which I brought with me to my behavioral interview with one person. After that I had a case interview with two people. Finally, there was a group interview where we had to build paper airplanes to exact specifications and try to fly them. I was an MBA candidate and there were mostly undergrads in my group, so it was a little weird, but it turned out ok. Just don't be a wallflower but also don't be obnoxious and domineering. I heard back within a week or two, but I think HR was mixed up because they sent me a full time offer. When I told them I was looking for an internship they sent me the internship offer.

There was multiple questions asked at once. Know about their company. They will ask you what you know about them. Do it in STAR. 2 people in the room. One was a intern before and one was the recruiter.
