Pros

The work environment is great: offices are incredibly thoughtfully designed spaces, coworkers are smart and caring, benefits are well above average, and the work is meaningful (ok, that last one is subjective, but almost everyone here believes in collaboration, openness, and a future where nearly every company uses a tool like Slack).

Cons

The primary (and only major) con is that the company is still trying to figure out how to operate at its current scale: there is friction between teams as goals and priorities are not always clear, the work planning process changes every quarter, and there is some expected thrash as projects are not always smoothly initiated or completed.

Pros

Slack cares about their employees as much as their customers. Extremely pleasant work environment, amazing colleagues and benefits, as well as an overall feeling that you're really valued. So much effort is put into making sure you have the tools to do the best work of your life, which, in turn, leads to a genuine feeling of fulfillment.

Cons

Career advancement has appeared to be drawn out at times.

Pros

Great culture of knowledge sharing. People are smart, helpful, curious and overall everyone I've met works hard and means well. Feeling that we're set out to build something great and deeply care about the customer. Oh and you get to properly use Slack!

Cons

Because there's so much growth, sometimes hard to know what to prioritize.
