Amazing culture, some of the brightest people I have ever worked with and great vision for growth.

Pros

Great product vision, inspiring CEO and founders, strong market, good work-life balance (varies a bit by department), cool and interesting problems to solve.

Cons

Several very poor management/organizational choices have been made in the past year, which has greatly diminished the company culture. This is especially prevalent at the senior/mid-manager level (along with a few notable executive hires as well). As a result, several departments have developed toxic cultures, leading to a host of employee departures. Attrition in the past few months has been particularly abysmal, with many key employees leaving or on their way out the door. While some of the turnover and change is normal for a fast-growing company, Slack's cultural issues go past anything most of us have seen in our careers.
