Pros

Slack is full of highly motivated, smart, empathetic employees who look to build on each others strengths and make amazing products together. We live and work in the Slack product so we are dogfooding all day, every day. We want to make work easier for our users and live the mission. The company is grounded and centered in the best outcome for its users and support its employees (especially during the challenging times of covid-19), at an impressive level. Slack might be based in the Bay Area but it lacks some of the bad reputations of other tech companies in the area. A breath of fresh, exciting air!

Cons

We work hard and some people work long hours but it comes from the drive and motivation of the product and is never forced/required by upper management. I really can't think of any other cons!

Warm, inclusive, playful engineering culture (that still ships great software)

Pros

The engineering culture at Slack makes special efforts to be warm and inclusive and sane. In particular, "work hand and go home"... or during covid, "work hard then stop working." We encourage working sustainable hours, except for when absolutely necessary. The massive social workspace with amazing active channels (#dogs, #trash-pandas, #cooking, #baking, #sf-classifieds) provides a way to make real connections with people in the company who you might not otherwise interact with. We ship software that people want to pay for!

Cons

So. Many. Channels. It can be exhausting to figure out which channels to actually pay attention to, and how to keep up with channels while also getting work done. Using hack is challenging because there are hardly any public resources or tools for it.

Pros

Slack is a great place to work. The team is incredibly smart and capable, and the market opportunity is massive. I truly believe we can reach every knowledge worker in the world, both because of Slack the product and the people who work here.

Cons

Competition and change! People love email and convincing them to use Slack is the biggest challenge we face.
