SpaceX Mechanical Engineer interview questions

Rigorous, quick follow up questions, first principle and fundamental grilling. Many conceptual scenarios. Process goes for roughly 5-6 rounds, ending with a presentation onsite. Recruiter first round, then speaking with various members of the team.

In person interview at my university with an engineer who was on campus for a recruiting visit. Asked me to talk about a project from my resume, and then asked me three technical questions.
