SpaceX Mechanical Engineer interview questions

First round was a 'heartbeat call' just to make sure you aren't lying on your resume and to get some logistical information. The second round is a 30 minute 1 on 1 with a hiring manager in the applicable division. Most of the call was about the experience I have and some technical questions regarding my current position. After that I was asked one technical question which I failed.

The interview was an initial recruiter screening, then 2 interviews involving technical questions and discussing my experience. Then an in-person presentation, followed by panel interviews and a written exam for which you are given 15 minutes.
