Phone screening was just questions about myself, why I was interested in SpaceX, some questions about my education, my past, things on my resume. Second interview started out behavioral and then quickly went into questions about my Master's program and my research very granular questions. The last interview was also very technical and scarring the only real question I remember was the final question about the Starlink (that's what I would have worked on) and interviewer asked presented me with the problem being faced with solar panels in space and what type of materials I would use to build new solar panel to improve the existing design and fix some of the problems that could occur in space
