Had a screener followed by four separate interviews with different people on the team. Three were technical, the last one was a presentation I gave to a panel and then received questions.
Interview questions [1]
Question 1
I had built a balancing table with a resistive touch pad on top of it. You could place a ball on it and it would balance the ball in the center. They asked how the system would respond if you hung a heavy weight from one side of the table.
I applied online. I interviewed at SpaceX (Brownsville, TX)
Interview
Asked technical questions regarding basic college engineering fundamentals, asked engineering portfolio questions regarding previous internship and project experiences, and asked hypotheticals based on what areas were owned on those projects.
First was with a lead engineer (technical), then with a recruiter (behavioral), then with another lead engineer (technical), future would have been on site. It was a very accelerated timeline and fast process.
