Pros

The office is probably the only thing that is a pro

Cons

Everything else. They show that their employees matter through empathy, compassion and so on. Further they preach about these amazing values during the on boarding. But that's where it stops.

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.
