General Atomics interview questions

Received a screen call from one of the lead engineers in the group and answered very basic questions. I was brought in about 2 weeks after the initial screen. I was first interviewed by an HR recruiter who asked very basic questions about my career goals. From there, we went to an interview room where I was administered a written exam and given 45 minutes to complete it. Questions involved identification of basic discrete components, op-amp formulas, digital components, and power systems concepts. Some questions were very easy, some were difficult. After that, i was interviewed (non-technical) by a lead engineer from the TE group for about 15 minutes. Waited an hour, then was interviewed by a manager from the field engineering group. He opened up some schematics for a flight board and pointed out various circuit components (mostly op-amp based) and asked me to identify them. This lasted about 15 minutes. Waited another hour, and my final interview (non-technical) came from the manager of the group. The entire interview process lasted from 8am to 1pm. They gave a tour of the facilities following the interview. Received an offer 2-3 weeks later, and accepted.
