      Pros

      Pros -Culture is strong, and there's a lot of passion for the product. -Co-workers are very friendly and helpful. -The company itself is very successful and continues to grow on that path.

      Cons

      Cons -Some of the leadership is a little under-qualified, and it shows. -Benefits could be better, but maybe that's why we still have so much money left in the bank? Catch-22 situation. -There's a distinct lack of transparency as we continue to grow larger, and it's unfortunate because that was not the case in the beginning.

      Strong product, downtrending culture

      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.
