I'd love to work there. Just had a friend interview in fact (didn't quite make it but enjoyed the experience). The only concern is salary and working conditions. I mean I get the impact of the work and it is true that is by far the most important consideration for any engineer. But I have worked for smaller companies before where salary was well below average and there were 70-80-90 hour weeks. It was incredibly demoralizing. It would be nice to hear that isn't how SpaceX is.
