SpaceX Manufacturing Engineer interview questions

The process started with an unscheduled phone interview with a technical recruiter. She asked me a list of about 10 questions about general physics principles regarding the position I had applied to (~30 min). Next was a 45 min phone interview with the lead engineer for the position I applied for. He asked me much more open ended, engineering questions. Most of them had to do with the basic principles taught in college and how they pertained to projects that I had worked on either in school or in internships (beam bending, stress/strain, vibrations, equations of motion, etc.). The process concluded with an on site interview that lasted ~4 hours with a 30 min technical presentation on a school/internship project. And 4, 30 min interviews with members of the team I was applied to. Half of the interviews were about my technical/engineering accomplishments where I was asked to specifically explain the engineering principles behind them. The other half were about my work style/desire to work at SpaceX/teamwork experience.

After submitting my CV through the company's website I was contacted by the recruitment team within a couple of days to discuss my background. This led to a couple of phone and Skype interviews with members of an interested team. Shortly after this, I was flown out to California for a day of face-to-face interviews which involved giving a 20-min presentation on a personal technical achievement, some 1:1 interviews and a tour of the facilities. All through the process everybody was extremely friendly and accommodating. The interview day was challenging but very fair and I feel like I learned a lot from the experience.
