SpaceX Test Engineer (Mechanical) interview questions

The process started with an internal recruiter reaching out to get a baseline of experience. I next spoke to a member of the team for 30 minutes and was asked some standard structural engineering questions. After that, I made it to the second phone interview where I met with two members of the team for 30 minutes and was asked some pretty technical questions. I didn't come up with the right answer, so I did not make it to the final round.
