Pros

• The people - This is what attracted me to the company initially and it's what's kept me here for almost 6 years. Collaboration skills are considered crucial, and toxic lone wolves don't last long • The product - It's really fulfilling to work on something that so many people use and rely on. • Strong commitment to diversity and belonging, since the earliest days of the company - This is something that everyone cares about, from the CEO on down. There will always be work to do here, but we're doing it with a deep-seeded cultural commitment • Hard problems to solve - In Engineering, there is so much work to be done. We're reaching levels of scale that require novel solutions; off-the-shelf approaches won't work. Add to that adoption by the largest companies in the world, distributed across the globe, and it makes for some meaty projects

Cons

• If you aren't aligned with the culture, you will probably have a tough time here. Read the @SlackHQ Twitter account or slack.engineering blog to see some examples of the culture. If that's not for you, then it will be an uphill fight to find happiness here • It's a crucial service for most of our customers, so if something happens to impact that, it's priority number one to fix it. If you don't like being on pager rotation occasionally, steer clear • You can probably get higher base salaries elsewhere. If you don't think the stock has a lot of upside, then the numbers probably won't look that good to you.

Pros

Great culture, hardworking people, great projects, wonderful leadership, amazing compensation. I could go on and on! Seriously the best company I have worked at. For anyone on the outside looking at this review - dont think twice - apply.

Cons

Nothing much really but we could do a better job stopping MSFT's false narrative. Also we need to be more proactive weeding out incompetence and incompetent employees.
