I applied online. The process took 4 weeks. I interviewed at SpaceX (Cape Canaveral, FL)
Interview
I had a 30 min initial phone screen with HR, two 30 min technical phone interviews. I then gave a 1 hr in-person technical presentation followed by 4 more one on one interviews. Executive approval is the final interview step.
Interview questions [1]
Question 1
What was your greatest technical achievement and why?
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.
