They are flexible with many different things which makes working there very rewarding and allows a strong work life balance.
Cons
The company moves very quickly and sometimes the transitions can be rough. They usually work once all the changes are adjusted for but there is a constant change. It is a product of the start-up culture but can be temporarily disorienting in its speed.
