I applied through a recruiter. I interviewed at SpaceX (Hawthorne, CA)
Interview
One recruiter behavioral phone screen -> Two technical calls -> One full day technical panel interview onsite
95% of the questions were technical, and will tap into your knowledge and past projects
Interview questions [1]
Question 1
Describe your past projects, what did you do, what did you accomplish, and what would you do differently
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.
30 min call on personal projects and technical questions with recruiter. Technical questions were relatively simple and focused on engineering fundamentals, about cantilever beam, incompressible/compressible flow, and ideal gas questions.
Interview questions [1]
Question 1
How does flow velocity of an incompressible fluid that is in a pipe change when there is a constriction in the pipe?
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.
