I applied through my school system. The interviewers were actually very friendly and collaborative. Prepare for some basic interview questions and you will be fine. I was interviewed one by one with each of the people in the team.

Called me in, went in for an interview and the conversation was fair/ok. There didn't seem to be a structure/person to report to for the internship, despite questioning it. The manager firmly said they would get back to me within a few days, but never heard back. Wouldn't work there
