Pros

Great culture of knowledge sharing. People are smart, helpful, curious and overall everyone I've met works hard and means well. Feeling that we're set out to build something great and deeply care about the customer. Oh and you get to properly use Slack!

Cons

Because there's so much growth, sometimes hard to know what to prioritize.

Pros

Wonderful culture: humility, empathy and just plain good natured personalities abound. Having worked at many large, high profile internet companies the hardest thing to get used to is .. Yes, these people are also very very smart and talented

Cons

Slack is essentially selling *reliability* as it's main feature, and when it comes to scalability problems, reliability is the least fun (compared to fast, big and kinda reliable i've had at other places) .
