Pros

Slack is selling a game-changing product that changes the way that people communicate, get work done and feel belonging at work. The team that the company has assembled is bar none - people truly smart, collaborative, humble and hard-working. I learn from my peers and team every single day, and I am proud to be part of a winning team.

Cons

The cons pale in comparison to the myriad pros.

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
