On-campus interview: I waited about two weeks before hearing back.

They were very nice and flew me out to Seattle. There, I had a chance to interview with four different teams inside of Cloud and Enterprise (one of the organizations within Microsoft).

All interviewers were nice, though one was slightly more serious than others. However, all of them made me feel comfortable.

I had a fairly different experience regarding questions. Most of my friends were asked things you'd find in CTCI, but I was asked very weird, eccentric questions.

You should be comfortable with thinking on your feet if you're interviewing with C+E, because chances are you've not seen that type of question before.
