SpaceX Engineering interview questions

One phone interview, 30 mins. Then HR forgot to call me for a few weeks to tell me that I got it. Generally very easy and straightforward, the engineers conducting the phone interview were clearly busy and stressed. Also they often shuffle interns to end up working for a different manager than the one with whom they interviewed.

Half hour interview, they called precisely on time. Grilled me on my technical experience and decision making for 20 minutes. 8 Minutes of me asking questions until I delved into proprietary secrets.
