Pros

Slack has a beautiful office in SF which is one of the most wonderful offices I have worked at Aesthetically. Good Co-workers who are nice and work together collaboratively

Cons

Everything else especially Management. The Management is very traditional, and has low diversity although Slack stresses on being a very diverse culture and tries to portray this via Social Media or Articles however internally that's not very true. There are no Managers who I can relate to who, like other Unicorn startups are less traditional, new generation, energetic and diverse. I also wish we had a more Front End specific Managers because most Managers here are not very good at Front End Engineering which causes discussion gaps between Engineers and Managers.

Horrible data organization

Pros

Perks are great. Building is beautiful. Slack, as a product, is useful.

Cons

Data org has no strategy or vision. Most engineering managers don't care about their team members. The very few who do aren't supported by the senior leadership. No focus on engineering quality and the happiness of the engineers. VPs and directors overpromise to the execs. They get upset when their unreasonable demands aren't met. Horrendous amount of cross department politics. Constant on-call issues and pages. Small teams supporting large number of projects and constantly struggling to keep up. No appreciation or recognition of th good work. CTO belittles the data org when things go wrong. He seems unhappy with the team, but does nothing to understand and correct any issues. I can keep going but hopefully you got the idea!
