Very interesting. I wasn't really asked any real questions apart from about my grades. Very conversational, I led the conversation for the most part, so I was kind of worried they had already made up their mind.
Very simple, initial behavorial interview, then final round consists of back to back 30 min interviews, only behavioral. If you prepare you will do great, make sure to do your research on the interviewers.
It was all behavioral and it consisted of questions regarding your resume and past internships and what you hope to get out of it if given an offer to work for them.
