Recruiter was nice, but kept backtracking and changing details about intent and job description based on my responses. They asked that I "make sure to be enthusiastic about how lucky I would be to work there" during the next interview. Interviewer was late to the call and to my responses. Not a good sign about how they handle things there.
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
