I originally was called by the manager and we set up a phone interview for an internship. I did not receive an offer at that time, but I called back when I was nearing graduation and they had me come in for an interview. I was interviewed by three or four of the engineers working there. I was asked the general questions but the questions that stood out were, "How to find the current flowing through this circuit diagram" and "How would you heat this room? Show me."

Interviewed at Career Fair, was a direct recruit/hire out of school. First interview team was two people, second Interview team was extensive (5 team members), and the questions were thorough about your engineering understanding of systems. Overall was nerve-wracking but the interviewers were nice.
