Pros

- The environment and culture are great! - Flexibility and work life balance are very well managed at Slack - Benefits are very convenient - Open for ongoing enhancement and re-evaluating latest techs and how to make things work better

Cons

- Maybe some legacy code that needs some work but I see engineers already doing great effort to resolve this over time.

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.
