Pros

Slack operates like a start-up in many ways. You can have impact, make changes without bureaucracy, and work in a fast-paced environment. At the same time, Slack has the stability and work/life balance of a bigger company. I've been able to learn a ton during my time here.

Cons

We are definitely still figuring things out and building. Things are often ambiguous, and part of the fun is figuring out how to operate in ambiguous situations.

Pros

- I've worked at companies with very smart people and I've worked at companies with very kind people. Slack is the first I've worked at where my peers are very much both. - Culture

Cons

- The growth of company has resulted in lots of restructuring and constant change, which in itself is not a bad thing, but is a source of stress.

Pros

Management really cares about you. You'll work with the smartest people you have in your career and you will work in a fast-paced space with an incredible opportunity.

Cons

The only real knock I have on Slack is being an employee in a non-SF office. The world seems to revolve around SF and it can feel like if you're not in that bubble you are lost in terms of recognition and more importantly career opportunity. I think this is something being addressed and feedback that is heard but as of right now this is still a sore spot for me.
