Pros

Slack was the absolute best place to work pre Salesforce acquisition.

Cons

Impossibly fast change, questionable leadership decisions, product decisions feel half baked, absolutely enormous company with frequent layoffs. You're definitely just a number here.

Pros

If you don’t care most employees and managers don’t care either. Since the merger rest and vest is a way of life

Cons

If you are actually a qualified employee who values work ethic steer clear. They promote DEI above everything else. If your colleague is part of that collect them all set then their career is set even if their abilities are two levels below where their title says they should be. Females made up 25% of the engineering force but 50% of promotions one year, If you were not DEI they didn’t even consider you. Basically if you are looking to work with the best and brightest peoples you ever will in you career… steer clear you will be sadly disappointed.
