Very simple interview, I was called by a project engineer on the team for an average interview, no difficult questions. I didn't hear anything back for 2 weeks until I was called again by a senior project engineer, interviewed for 20 minutes, where he hardly asked me any questions, and then he offered me the position.
Only bad part was that I was never emailed about the position, both of the phone calls were completely random with no heads up, I was laying in bed sleeping during the first one.
Overall, very easy interviews and very easy to talk to people.
