General Atomics Mechanical Engineer interview questions

Applied online for an entry level position and was contacted by HR in consideration for different engineering position. I had a phone interview with recruiter and a week after onsite interview with 2 hiring managers. I was also contacted by relocation department before my onsite Interview which I though was a good sign as I was assessed on relocation before any job offer. After the interview I felt I had a good chance at the job opportunity. I sent a thank you letter right after and follow up with recruiter 2 weeks later with a voice mail and did not get a reply.

One 10 minute conversation with HR. Panel interview with hiring manager and two other team members. Very specific questions, not really any behavioral ones. Had to get 5 references to fill out survey about skills and qualities.
