High quotas tied to Agentforce & Data Cloud - not even the top performers are at 40% to quota right now

Pros

Great benefits, flexible work/life schedule and opportunities to innovate. I work on a very collaborative team and have a great manager.

Cons

Priorities can change, so don't be married to any one idea or project. Slack is constantly testing things that never ship in the spirit of making sure what ends up in customer's hands is the right choice. Leveling up is hard - their criteria is quite intense compared to other companies.
