Pros

Slack is a place where you have can really do your best work. There's lots of room for growth both within and across departments, the people are amazing, the space itself is immaculate, the culture is vibrant and inclusive, and there's no shortage of challenge.

Cons

Things move quickly! If change is tough for you to handle, this probably isn't a great fit.
