Pros

Slack has a very good atmosphere throughout the whole company and the people are very supportive and helpful. You can always reach out to the management. The hierarchy is definitely flat. For a Sales Position, they definitely don't put too much pressure on you and put more emphasis on quality than quantity.

Cons

The one thing that really bothers me is the career progression. Slack has many talented young sales people that would be ready for more responsability and the next step. And although Slack is growing substantially, they prefer to hire externally. I am sure that this is a genereal problem in the Tech Industry, but it makes an awesome employer only a good employer.

Pros

Plenty of opportunity for growth. Leadership is close to the work, personable, and very human. Response to changes in the world are positive. Understanding of family needs, and monthly Friday company holiday have been nice.

Cons

Most people seem overworked. Political views and opinions find their way into conversations and internal comms often with strong liberal leanings, lending itself for an uncomfortable environment for conservatives, and libertarians. Alternative opinions get shut down with no consequence.
