I was flown to the Hawthorne office to give a one hour technical presentation, followed by eleven 30 minute interviews. Some of the interviews were technical, some personality. Four of them had me down on the factory floor talking about various components of the rocket. The rest of the interviews were in a small conference room with whiteboard walls. Most of the interviewers had me explaining projects I'd done in the past, and the whiteboards were a huge help. I met people who would be on my future team, including my future manager. I interviewed with everyone from brand new employees (4 weeks in) to a VP who had been there 10 years.

The interview process for spaceX is meticulous. They have several rounds and ask college knowledge of engineering principles. Be sure to brush up on these before going into the interviews
