SpaceX Mechanical Engineer interview questions

very rigorous and thorough. kept on asking technically questions regarding my projects and other questions. mostly looking at design process. asked a lot of questions roughly an hour long but takes longer if good questions are asked.

One call with a recruiter, 3 calls with engineers, then an in-person interview. Things were organized quickly and I heard back within a couple days of each interview (aside from the in-person which took a few weeks to hear back).
