Pros

- Lots of great, smart, hard working people at Slack. - Work on a product enterprise software users enjoy. - Competitive compensation plans.

Cons

- Very bad behaviour at the executive level (including CEO verbally assaulting employees in public Slack channels). - Highly political environment. The highest I've seen in Silicon Valley. (But people don't talk about it out of fear.) - No upward mobility (see highly political environment). - HR is there to protect executives/founders, not employees (but that's common). - High turnover in eng/product/design due to toxic work environment (so you will spend a lot of time interviewing to add to your team)
