I applied online. The process took 3 weeks. I interviewed at SpaceX
Interview
First phone call from recruiter involved typical questions regarding past experience, who you are, and why you want to work at SpaceX. Follow-up questions inquiring further into experience. Recruiter was friendly and made interview less stressful.
Interview questions [1]
Question 1
Tell me about one of your projects and your role in it.
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
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.
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.
