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)

Customer Experience

Pros

• Slack does Customer Experience right! We have a lot of freedom to do what is best for our users. This is a gem in the world of Customer Experience. • Great team and atmosphere, I work with a great lot of people, everyone's giving it 100%. • High-profile company, the product is amazing, and the benefits are very competitive.

Cons

• Don't be fooled by the no-blame, no-ego, we're-all-in-this-together approach. There is politics, like everywhere else. • The people at the very top of Customer Experience are control freaks. Their baby is growing up and they're having a hard time letting to. They are not receptive to disagreement, they get involved at a level they should not be and consistently undermine our managers. They don't know how to manage more structured organisation (or people it seems) and it can get messy and confusing.
