Brief phone screen with recruiter, then had 2 additional phone interviews with members of the team. Process took about 2 weeks before being ghosted.
The initial phone screen was straightforward: Why SpaceX? Tell me about yourself/experience. What is your GPA? SAT? Would you be willing to work 50+ hours? etc.
1st technical interview was more difficult than I expected. They asked more in-depth questions about my resume to test whether I measured up to what was on my resume. Then they asked fairly difficult questions on how I would design different test setups, what materials would be used, what parameters to consider. These questions weren't something you could prepare for in advance (best way is to just have a good grasp of mechanical engineering in general). At the end I did not believe I did well enough based on my responses, but I was contacted for a 2nd technical interview.
2nd technical interview, the engineer I interviewed with was 15 minutes late and came across as very disinterested and seemed strapped for time. I prepared ahead of time for their particular discipline, but they asked no technical questions and instead focused on my resume. I was told that I would receive a response shortly from the recruiter.
After a follow up email and receiving no reply back. I received a rejection email a few days later with no feedback. Very weird.
Interview questions [1]
Question 1
Why SpaceX? What is your GPA/SAT? Tell me about yourself? What kind of testing have you performed?
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.
