Talked to representatives during University career fair, got a phone interview 4 weeks later with a manager. Interview was simple, talk about your resume and experience, plus some technical questions. Got a 2nd phone interview with another engineer in the same department. Interview for ~ 1 hr, very technical interview, talked mostly about what was on my resume and went on detail about it. Be ready to know in-depth knowledge of what's on your resume and link it to how it will be useful at SpaceX. On other words, know what you are talking about, no hand-waving.

40 minute long call with an engineer. First, we mainly talked about my experience within a technical organization. Followed up with rapid fire technical questions and then he asked for any questions from me. We had some extra time left over and he gave me the opportunity to talk about the next most important on my resume
