Pros
I joined Slack 1.5 years ago and can honestly say that Slack is the best place I have ever worked in my career by far. Slack has a very unique blend of the following components which make it (in my opinion) such a great place to work: 1) Thoughtful and humble internal culture 2) Incredible leadership that puts the wellbeing of the employees first 3) Very intelligent, talented people all throughout the company 4) Slack's platform is driving huge transformation in the market, not to mention fun to use for all that we do
Cons
Working in a hyper growth environment can be challenging as certain processes may not be mature (or even in place for that matter). One can also find themselves wearing many hats, which can be challenging if one does not brutally prioritize and manage their time and personal well being
