I applied through an employee referral. The process took 2 weeks. I interviewed at SpaceX (Hawthorne, CA) in Aug 2013
Interview
Tech screen by HR, 2 technical phone interviews, 6-hour on-site interview with 5 one-on-one sessions (2 tech, 3 not) and provided lunch.
Phone interviews are to establish proficiency and basic coding approach.
In-person technical sessions were split: one more daily-problem oriented, the other about known algorithmic solutions.
Non-technical interviews were personality / philosophy / social.
Feedback time between each step was 1-2 days.
