There is initially an small interview, which happened at my university, where they ask you basic logic and algorithm questions to see if you can solve problems on the spot. They also ask you some basic programming concepts, the kind that reviews on glassdoor already detail. So therefore I was already aware of the kind of programming concepts that were going to be tested. The interviewing was good, what turned me off was the interviewer. He wasn't unfriendly, but he wasn't friendly either. In short, his demeanor didn't encourage interaction. The reviews I read on glassdoor were contrary to that, so I think this interviewer and/or interview may be an outlier. I was not invited back for any further interviews.
