I applied online. The process took 2 weeks. I interviewed at SpaceX in Dec 2018
Interview
Initial phone screen by HR followed by two technical/behavior interview by technical managers. Really in-dept questions about projects on your resume. Overall the process was smooth but the interview was difficult.
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
