Pros

I have never seen a company so dedicated to its values. I know, I know, every company has a list of values and principles and claims to live by them blah, blah. But at Slack, it isn’t really any list of values, so much as it is an implied way of being. If you are collaborative, respectful, put team first, find creative solutions, the. You will be more successful here. In some cultures, that simply isn’t true - over time you get sucked into the grimy, political necessities. I have seen it, fallen victim to it, and I am never going back. Working at Slack, I feel liberated to to my best work. Stuart is amazing. The hype is real. Finally, I work in Sales, which is often the most competitive dog-eat-dog side of a company. Not here. We win together or we don’t win at all. I know it sounds crazy, but come see for yourself.

Cons

Typical growth challenges. We use Slack for EVERYTHING at work and once in a while, there is a better way to get something done.

Cons

The company hierarchical. Management does not listen to or take their employees seriously. Folks draw a circle around their responsibilities to minimize liability. The company smokes their own product, meaning that they are great because they believe they are great. Management is green and has no clue how to deal with friction within the team or how to motivate people. The product has serious issues, but if you bring them up along with possible solutions, you manager will not be happy and tell you that these issues are not our concern because a different team is responsible for the feature in question. There is no sense of urgency. The company is very successful, but resting on your laurels is an invitation to competitors to eat your lunch. The product does not scale well on the server-side. The word "proactive" is not in anybody's dictionary. We're all waiting for fires to fight. Teams are poorly organized. Instead of forming small two or three person teams to implement a feature, some people are assigned massive tasks while others are given small tasks that have to be stretched out to make an appearance of effort. Some teams can have three or four managers in the span of a single year.
