SpaceX Propulsion Analysis Engineer interview questions

I ended up interviewing for three different positions, two of them in propulsion engineering. I applied online at the beginning of September and then attended my school's career fair. The recruiter was able to pull up the application. We had a 20 minute or so conversation about SpaceX, the intern experience, my previous work/research experience, and why I was interested in the company. Technical questions were asked about my experiences. I didn't hear back until mid-October when I interviewed for a build reliability position. After about another week and a half I heard back that I did not get the position. I was contacted again mid-November to interview for another position, this time in propulsion. The interview was technical and lasted about 30 minutes. I interviewed for another position a week later. The interview was also technical and about an hour long. I heard back a couple of days after the third interview that I had gotten the second position.
