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!

Pros

Slack has a beautiful office in San Francisco. Almost everyone there is very nice and wants to see you succeed. The perks are nice, especially the weekly massages.

Cons

I had 3 managers (4 if you count the time I had no manager) over ~6 months. The whiplash was disorienting and I couldn't focus or get my work done. My original manager was amazing, his replacement was bad (overcommitted, late to everything, bad listener) to the point that I quit. I miss my teammates but I don't miss him. Additionally, when I was leaving, I found that multiple coworkers had tried to transfer out to other teams at Slack and had been denied by the director of our department. IMO, that's unacceptable. The pay isn't great - relatively low base pay for a company their size plus a yearly bonus that the finance department threatens to take away at every all hands.
