Received an email to set up a pre-interview phone call. Basic aerospace degree related questions, pretty easy. In addition, they asked trivia on space-related events.
Passed, received another email to set up the real technical interview. This one I got pretty beat up on. I answered maybe half the questions, and that was shaky. Probably because I'm pretty fresh and they were looking for 3+ years experience; some of the questions were more mechanically focused.
It was a group of 5 engineers over a span of an hour. They were very nice and kind.
