Vantaggi
The most rewarding aspect of working at SpaceX is the impact factor, knowing that I'm contributing, however small, to a cause that will advance civilization and lay down the foundation of space exploration. The work environment is open and friendly. The work itself, although high pace, but is self-managed. You're given some projects/tasks and let loose. The manner in which the projects/tasks are completed determine your qualification of getting the 2nd internship, or transition to new hire. Other perks: free coffee, yogurt, fruits, and gym membership. There's a full menu served at multiple locations for all meals. Main meals are relatively cheap ($3-$5!). There's so many to list as pros for working at spaceX, but my main one is the projects itself and that's enough to outweighs the challenges I've encounter so far.
Svantaggi
One big con of working at spaceX, Hawthorne is its location. Although indirectly related but plays a decisive roll when weighing options. Traffic, high cost of living, smog, and more traffic are common complaints.
