Several years back I interviewed there and got to say I was very impressed with the hands on stuff they were doing in house. They definitely low ball the offer and leverage on the passion that some might have. So, in short if you are really really passionate about space industry then this is the place to be at. You will get your hands dirty and work on a wide variety of issues.Good luck!
They're the only company I've encountered that insists on a Bachelor's Degree for Dev positions... relevant experience need not apply. I've been black-holed twice now by recruiters (who reached out to me!) once they learn I have no degree.
Which is a bit funny because there's some famous interview clip out there with Musk saying he doesn't care if someone has a degree or not.
A friend interviewed there and got a low offer. His impression was people there are stressed and bust their asses for lowish pay. Why? Because they are fanboys and fangirls. Not trying to be insulting. Probably a super cool feeling to be creating the future.
