SpaceX was the only job I was applying to, as my current position is pretty awesome. They were accommodating to my work schedule, and when I had to reschedule a phone screen, they were understanding.

I got the sense that SpaceX is much more like a Silicon Valley company than an aerospace company. This was particularly attractive to me, as I've been working for big tech companies.

There are some really sharp people working at SpaceX, and they all seem enthusiastic about what they're doing. They made it clear that long hours are expected, but that they're also working to reduce the overall load on the engineers.

All the questions were standard software engineer interview questions. SpaceX doesn't assume any domain knowledge, so I didn't have to explain how orbital mechanics work or anything like that.
