Pros

Supportive engineering culture. Good perks but not over the top and professional. Good work-life balance.

Cons

Rapid employee growth means a lot of people are new and few people seem to have in-depth knowledge. Development pace can feel a bit slow coming from a smaller company. Overly-cautious about unit tests and logging, while lacking in integration and system tests to prevent incidents.

Pros

Truly value diversity, good work life balance, low egos, very good but not fantastic benefits, everyone tries to abide by the values: smart, humble, hardworking and collaborative. I've been at 5+ tech companies and Slack has one of the best cultures I've seen. I genuinely like everyone on my team and everyone I've met at Slack outside of my team. Everyone is willing to pitch in and help with things.

Cons

Since they only use Slack to work it can be difficult to find information you're looking for sometimes.

Pros

The work environment is great: offices are incredibly thoughtfully designed spaces, coworkers are smart and caring, benefits are well above average, and the work is meaningful (ok, that last one is subjective, but almost everyone here believes in collaboration, openness, and a future where nearly every company uses a tool like Slack).

Cons

The primary (and only major) con is that the company is still trying to figure out how to operate at its current scale: there is friction between teams as goals and priorities are not always clear, the work planning process changes every quarter, and there is some expected thrash as projects are not always smoothly initiated or completed.
