I applied online through an employee referral for a different position, but after a phone call with the recruiter, the falcon 9 manufacturing team requested an interview. I had two phone screening interviews. The first was with a manager and lead engineer from the manufacturing group. It was primarily focused on my resume and portfolio that I submitted. Asked questions regarding certain engineering decisions and methods to mass manufacture certain parts. Asked how I'd optimize a certain design by keeping the performance, but reducing the weight of the component. Another question was about the performance effects of adding a certain component to the system. The recruiter calls later saying that they wanted to do an additional technical phone. Interviewed with a structures engineer, similar format. Asked about academic transcript and certain questions about resume and portfolio. Asked why certain fabrication process was chosen and why choose a certain material in our design. Then asked the beam question. I messed up the follow up question by fixating too much on two potential solutions and completely disregarding the third. I did not effectively state my assumptions and that bit me in the butt. I get a call the next day that the team did not want to proceed with my application. I knew by the end of the interview that I would not get the job anyways.

Phone screen with recruiter followed by two phone calls with engineers and then an on-site interview where you present a presentation on a topic of your choice. Also other technical interviews on site as well.
