Very unfriendly interviewer. Told me that the internship was not a training ground and I should I read this and that before coming. I get that you do not think I have the ideal experience or did as much research as I should have, but no need to get nasty. Reflects badly on the culture if you can't even be polite or act polite to a stranger and a student.

3 rounds. 1st round was technical questions, 2nd round was half technical questions and half fit questions, 3rd round was fit questions. Took quite some time in between, about 1 to 2 weeks
