Pros

Working at Slack exceeded expectations in the form of great people, great product and thoughtful culture and operations

Cons

The Salesforce acquisition majorly changed Slack’s culture and foretold the exit of a number of key leaders. The Slack product was more difficult to tell once the Slack teams were considered part of the Salesforce extended team.

Pros

Love the majority of slack employees I work with

Cons

Salesforce feels like a cult with animated characters and a huge love for appropriating Hawaiian culture (and Salesforce owns slack and forces their culture on Slack)
