Pros

I've been at Slack for almost 4 years and the thing that has kept me here is the product. My colleagues are a delight, but the best part of my job is talking to customers every day about a product I believe in wholeheartedly.

Cons

All the normal scaling pains and trade-offs. Nothing unique to Slack and better managed here than anywhere else I've been.

Pros

My favorite thing about Slack is the folks I get to work with. My team is amazing and I love being surrounded by such a smart and diverse group of people. Leadership gets a lot of things right, the benefits are amazing, and work life balance is much better than a lot of other places I've been.

Cons

The biggest quality of life issue is the relatively fragile and monolithic codebase. I'm lucky enough to spend my time working out of the monolith, but it's there and it's big and it leads to incidents. We do have a healthy culture around incidents (postmortems, etc) but life would be better if we reduced the amount of time we spent on them.
