Pros

Great coworkers. Leadership open to experimentation and feedback. Relatively transparent with exec decision making. Fantastic benefits. Reimbursement for professional development is helpful. Flexible PTO scheduling with enough advanced notice. Generous COVID-19 support for employees, especially folks with children. In the past two years, company has shed a LOT of the startup culture shticks. An culture that encourages and rewards employees who excel at interdepartmental and external collaboration.

Cons

If you are uncomfortable with change to organization policies (mostly to accommodate rapidly changing global health, social,economic or political climate), this might be a challenging work environment, at least for the first little while.

Pros

Slack has changed the way I think about company culture, transparency, diversity and how companies can make a world a better place. The opportunity Slack has to further change the world seems almost boundless. If that sort of thing is your jam, Slack might be the right place for you.

Cons

Majority of engineering based on in the Bay Area, however that's changing with a remote first culture
