Pros

Great culture, hardworking people, great projects, wonderful leadership, amazing compensation. I could go on and on! Seriously the best company I have worked at. For anyone on the outside looking at this review - dont think twice - apply.

Cons

Nothing much really but we could do a better job stopping MSFT's false narrative. Also we need to be more proactive weeding out incompetence and incompetent employees.

Pros

Slack is a company filled with hard-working, caring, and hilarious people that are committed to doing great work. You'll find that you are welcomed to the company with open arms and any team you join makes sure that your transition to the company is as smooth and enjoyable a possible. The problems that you work on are both challenging and fascinating, and the product itself is just such a pleasure. What I find most admirable about Slack, however, is their ongoing and renewed commitment to helping those less fortunate and fostering diversity within the company. Slack is one of the few companies in which I have seen a Black and Latino women make up a good portion of the engineering managers. It's inspiring and necessary. All in all, Slack is an amazing company. I am so lucky to work here.

Cons

As someone who is relatively new, I feel like I am not experienced enough to comment on any things Slack needs to improve yet.
