SpaceX interview questions

Contacted University recruiter via LinkedIn, told me to apply online and to forward him a copy of my resume so that he could keep tabs on me. Contacted for technical phone interview with a manager. Contacted the recruiter again asking for advice. He told me to keep doing whatever I was doing because it was working and the interviewer had written positive things. Then had another technical phone interview with a director. Both interviews were a little intimidating just because i really wanted the internship and I only have a year of college under my belt. Questions started open ended, then became increasingly technical as the interviewer probed my knowledge. The weren't super talkative, but I didn't take it to mean they were impolite, just busy people who have important things they need to do.
