I applied through a recruiter. The process took 2 weeks. I interviewed at SpaceX in Aug 2025
Interview
The interview process is pretty demanding and thorough. It's a total of 4 interviews, the last one if you get there is in person. You are pitted against applicants at every turn, so be ready for that. The first interview is pretty straightforward. The interviewer asks some basic questions like tell me about yourself, why Spacex, 5 year plan, etc. They then go into a 20 technical question section where they see where you rank compared to other interviews and its about fluids, heat transfer, beam questions and material properties. They do tell you if you got it right or wrong though
Interview questions [2]
Question 1
Mainly beam questions like: Where is the max stress on a cantilever beam with an end load, when cantilevered, which shape has more stress, a circular cross section or a hollowed tube cross section, ideal cross section of a beam to limit stress, etc.
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.
