General Atomics Systems Engineer interview questions

Submitted application, got an interview 4 weeks later. Initial phone screening from a recruiter. The interview didn't go bad but I didn't move forward in the process, unfortunately. The recruiter did not seem familiar with the job posting.

I applied online and was contacted for a phone interview about a month later. After that, I was scheduled for an in-person interview 2 weeks down the road. I thought the interview went well. It was supposed to be with 3 interviewers but one didn't show up. It lasted about 90 minutes and didn't get too technical. Had more "describe a situation when..." type questions, in addition to general descriptions of the position. At the end they said I would hear back within a week. 2 weeks later, and they were "waiting on a proposal." 4 weeks after that, I was informed that the position had been cancelled. Disappointing end to a 3 month process, but what can you do?
