I applied online. The process took 2 weeks. I interviewed at SpaceX (Brownsville, TX) in Mar 2022
Interview
The first call I had was with a recruiter then the second is with an engineer for technical questions. They ask a lot of basic engineering questions so prepare accordingly.
Multiple rounds of interviews ending with an all day onsite interview. Asked questions about background, classic textbook problems, and coworker interactions. Very technical and difficult. Lots of time spent trying to understand your thought process
4 rounds, 1 with technical recruiter, 1 with engineer, 1 with manager, and onsite. first 3 are over the phone. onsite was the challenge, consists of presentation, one-on-ones, and tour.
Rigorous but fairly reasonable in my experience. The technical problems often has a twist but if you have strong fundamentals you should be able to perform well. The recruiter and interviewers I interacted with are all very nice people.
