SpaceX Build Engineer interview questions

Applied online through LinkedIn. Got an email from an interviewer to talk more about my experience on my resume. The interviewer was late, didn't apologize, and sounded unenthusiastic. Asked me one question that I explained in detail then asked me if I had any questions for them. After I found out I was not selected I reached out to the interviewer for constructive feedback and never got a reply back.

Initial phone screen, 2 interview w/ engineers on the team, got flown down to starbase but ultimately wasn't selected. Interviewees were chill and questions were pretty technical. Recommend reviewing first principles and engineering fundamentals.
