Pros

- You'll meet some amazing people here - Free meals, snacks, drinks, beer on tap, and onsite baristas - Great CEO who truly cares about the people working at Slack

Cons

- You will meet some very entitled people who complain that all the free food and drinks aren't good enough. Constant demands for catering to their allergies or sensitivities rather than just bringing their own food. Everything needs to be catered to them. - Constant temperature war. One person is too cold and demands the heat to turn on, one person is too hot, demands the AC on. Bring layers to this office. - Some employees are disrespectful to security guards, cleaners, and anyone else they see as beneath them. - Racism - Managers who do not fit the slack culture (screaming at their team members, insulting them, promoting toxic culture, etc.) but were hired because they have more experience than anyone on the team. - If you want to WFH, you'll be guilted/shamed into coming into the office - Does not pay as well as other companies - Have heard from others of their negative reviews on glassdoor disappearing Your experience at Slack really depends on your manager and team. You can have an amazing supportive team that truly believes and promotes Slack's message, or you have an awful demeaning manager that promotes a toxic culture.
