Pros

Coming from a smaller tech startup, the RSUs and benefits package seem insane. Very very generous. Co-workers and managers are very smart, friendly, and easy to work with. Executive team are good people with sound, long-term priorities. Obviously the product is excellent, and it's awesome to work on something with such a worldwide impact. The company generally walks the walk in terms of supporting remote work and work/life balance.

Cons

Lots of legacy code. Huge learning curve with regard to the technology behind the product, even as a relatively senior engineer. I've been here for a few months and still feel like I know next to nothing. Some of the deployment processes are onerous and slow, though it could definitely been worse, and it makes sense for a product that so many people depend on.

Great and transparent leadership. Excellent benefits. Competitive salary.

Cons

As Slack has grown, transparency has decreased, which is a shame IMO.
