First, I had a phone screen with a recruiter. The job was for nearly the same role I was doing on a similar program at a competitor. "I was pretty much a perfect fit," the recruiter said. Then, I had a really good call with the hiring manager, who also said I was a great fit. After that, I was sent over to someone for a technical screen. They asked me about 28 incredibly random questions, of which I calculated I had a 75% pass rate. I heard back from the automated system two days later that I had passed. The questions are posted below. I noticed not long after that this person was no longer with SpaceX, so perhaps others won't have a similar experience. The below questions took place across about 15 minutes.
