Generally, I look for a positive attitude and are they easy to work with, are people gonna like working with them? It's very important to like the people you work with, otherwise life [and] your job is gonna be quite miserable. And, in fact, we have a strict no a--holes policy at SpaceX. And we fire people if they are. I mean, we give them a little bit of warning. But if they continue to be an a--hole, then they're fired.
