The process essentially was a couple of Basic Technical Questions. Person was extremely rude and clearly did not care about the interview. I ended up declining second round and that is pretty much what happened.
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.
Multiple rounds of interviews ending with an all day onsite interview. Asked questions about background, classic textbook problems, and coworker interactions. Very technical and difficult. Lots of time spent trying to understand your thought process
