Pros
-Coolest people, projects, and sense of purpose of any company I have ever interned with. -Knowing insider info about Falcon/Dragon manufacturing and testing is really awesome. SpaceX has horrific internal encapsulation of projects so basically any employee can read about anything SpaceX is doing on the internal network. -Some groups (specifically mine) have a good work/life balance. People regularly worked 50-60 hours, but not much more as far as I know. -LA is awesome -Intern program is well run. Other interns are generally cool.
Cons
-This company is seriously white and male. I never felt unwelcome, but I imagine some do. In fairness, it might be harder for SpaceX to get diversity because of ITAR stuff. -Compensation is competitive, but below average. Particularly for the location (LA) and the fact that their employees are generally top-notch. -I think some groups go way over 60hours/week, mostly in manufacturing and MechE stuff. This is probably fine for a few years as a ~25 year old. Not a con for many space geeks but worth knowing for an outsider. -As an aspiring boglehead considering coming back full-time, Y u no 401K match?
