Pros
People are kind, helpful, nice to be around. There's quite a bit of independence in terms of what you work on and you go about accomplishing it. We're finally getting around to adding some structure within the organization (rolling out levels, we have people in HR and do perf reviews). We've also recently let go of some managers that weren't performing (note: not everyone who has left has done so voluntarily). I have a great manager and get along with her well. I get more feedback from her than any other manger I have to date and it's actually constructive and useful.
Cons
We're growing and nothing is perfect. There are systems and processes that aren't quite there yet, but we're aware of them and make efforts to improve weaknesses. There are some areas of the company which have higher hiring bars than others, there are some teams where the output isn't clear to the org.
