I interviewed at SpaceX (Boca Chica and Medford Colonia, TX)
Interview
Very kind. They made very nice conversation and related to me on a personal level before delving into my resume and technical questions. It's clear they work hard and love what they do.
Interview questions [1]
Question 1
Describe your project? Describe tooling, material choices, etc.
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
Rigorous but fairly reasonable in my experience. The technical problems often has a twist but if you have strong fundamentals you should be able to perform well. The recruiter and interviewers I interacted with are all very nice people.
4 rounds, 1 with technical recruiter, 1 with engineer, 1 with manager, and onsite. first 3 are over the phone. onsite was the challenge, consists of presentation, one-on-ones, and tour.
