Pros

Strong perks, good people, exciting product, great office location

Cons

The company is set up to fail from a data perspective, specifically from leadership decisions - extremely ineffective low-level managers that shouldn't be in a people manager role, a ton of politics, silo'd decision making, blindness to what is really going on from leadership (due to selective communication by certain leaders), and completely shaky infrastructure that sets up any team using data to fail. Directors and VPs changes their vision and perspectives week to week, demand deliverable turnaround within a day with no ahead notice, work is demanded that is unrelated to job roles, over-promising to the exec team and blame their org for not delivering, and failures to self-reflect any mistakes made.

Pros

Comfortable accommodations and benefits, useful product, smart coworkers (while they last)

Cons

Values are for display purposes only. Commitment to inclusion is shallow. The nail that stands up is hammered down. Sr Leadership are insecure and do not tolerate challenge, strong vision, or actual proactive improvements. Work-life balance is rapidly decreasing. Leaders are trying to squeeze blood from stones. Product is rapidly becoming unreliable and customer good-will being burned. Slack's early success was via taking the time to do things properly, now there is not even time to do things half-assed. It really shows when you use the product or try to have meaningful discussions with severely burned-out teammates.

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.
