      Pros

      Innovative product Incredible team across organization - smart, dedicated, energized, fun Empathetic organization Overall Slack is a wonderful place to work, and I have absolutely loved my time here.

      Cons

      Growing organization that is still finding its way from smaller start-up to now a 2K+ public organization. Sometimes processes can be overly tedious, and can feel like there can be too much of a big company mentality, when we still have the ability to be nimble if we could focus on that.

      World Class Culture and Team

      Pros

      Transparent leadership whose bottom line is _not_ to make a profit. I attribute a lot of the culture to Stewart. He is clearly very invested in social good initiatives (way before the pandemic started). For example, bringing in speakers to talk about racial justice initiatives, the last mile program, partnering with code2040, etc. The great part is that this culture attracts the best people! Folks that are incredibly kind and exemplify all of our values. Not only that, most if not all of the engineers are amazing technically. Technical leaders are very knowledgable and really level up their teams if not the entire org. There are also lots of opportunities to work on technical challenges.

      Cons

      The legacy codebase can be hard to work in sometimes, but it's getting better. The concentration of people of color and LGBTQ folks is not equal. Some teams are very diverse while others are not as much. The stock price is quite volatile, but trending upwards. We use Hack which no one really uses besides Facebook. Hard to find something as good for next job.

      Inconsistent Management -> Unhappy Engineers

      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.
