From the glassdoor.com reviews, its long hours and you're paid undermarket (which is fine if you want to work there, you're probably there because you want to work on something cool).

I applied to their Director of Infrastructure position having 14 years of IT experience managing people and large infrastructure and was told I was under qualified. YMMV.

I don't think a lot of SpaceX employees actually live in Hawthorne. Long Beach, Manhattan Beach, Hermosa Beach, El Segundo, etc.
