Pros

Remnants of the old Slack culture still exist

Cons

Most of the good managers and executives are gone. Culture has gone to hell. Salesforce is ruining the company. They want yes men/women.

Pros

Slack is a great product. It was fun to work on the product. They offer unlimited PTOs. Also full-remote positions are available.

Cons

Slack is not a tech company but a product company. Most of the middle managers are non-technical. This causes low quality decisions in system architecture, hiring, and promotions. They don't know what they are doing.
