I applied online. The process took 3 months. I interviewed at SpaceX (Kent, WA)
Interview
Went through 5 rounds of interviewing; the first one was with the recruiter, and the rest were with the hiring manager and senior engineers. It was probably one of the strangest yet most interesting experiences I have ever had.
Interview questions [1]
Question 1
Signed an NDA so can not disclose actual interview questions. However, a piece of advice that I would give is that no matter how difficult they make the question seem to be, do not over-complicate it.
