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.

Pros

I've been at Slack for 2 years and I feel very fulfilled. I really don't see myself leaving anytime soon within the next 5 years which is amazing given I'm part of Gen Z. I think the culture is what makes Slack stand out and while sometimes the workload does get intense and the diversity can be improved for people of color, I know Slack is doing its best and I appreciate it. - great culture - always shipping exciting features - feel very comfortable flagging issues to team and leadership - very clear direction and communication to employees - an appropriate level of big projects from time to time which pushes me to grow

Cons

- no Black or Latinx representation amongst principal engineers - no Black or Latinx representation in Slack leadership - salaries and leveling don't always look like they're fairly distributed
