Pros
The team is super smart and everyone knows their stuff well.
If you see an opportunity, you can take it and do it.
Flat structure, less authority means you can experiment and do as much as you want.
Cons
There's not much of an onboarding, so you have to figure things out. It can feel very sink or swim. Also, you have to work across many different time zones as well, because the team is global. Also, people have very short fuses if you don't pick things up quickly or not as smart as them.
