Pros

- Nearly everyone I worked with embodied Slack's values: humble, collaborative, hard-working and smart - Work hard, go home culture is live and well - Great place for growth

Cons

- Steady corporatization since Salesforce acquisition, less product-focused and more sales-focused - There are fewer and fewer left who were part of Slack's culture pre-acquisition

Smart dedicated people. Satisfying work on a product that is important to a lot of people.

Cons

Salesforce culture is very different than Slack's. Since the acquisition things have definitely changed.

Good place to work

Pros

* Fairly relaxed culture, by tech standards * Interesting problems, "big" data * Coworkers are nice and friendly people

Cons

* Some people are clearly coasting * Salesforce as a whole is not doing well (<10% Y/Y growth) * Random layoffs and poor communication from company leadership * In-office requirements of 3 days/week doesn't make sense for many (most of the people I work with don't even live in New York)
