Pros

Strong alignment across leadership, transparency, open communication and supportive culture. Slack creates a culture that enables collaboration, feedback and supports employees in any way that it can. I feel so lucky to work here alongside amazing coworkers and leaders.

Cons

None I can think of!

Pros

1. My coworkers are very supportive 2. So much greenfield in lots of areas of the product 3. A ton of work to be done 4. You work on a product many people love 5. Company benefits are the best I've ever had 6. I've been consistently busy/working hard since I joined 7. Lots of career growth opportunities 8. Lots of grass-roots efforts to improve overall code quality 9. We work hard, and then go home. You can hear crickets (not literally) in our Slack workspace overnight. Work-life balance really exists here.

Cons

1. Lots of engineers, not enough product managers or designers to unblock engineering's work so they are sometimes a bottle neck 2. The process of assigning work to engineers is not a well-oiled machine 3. Not a lot of process in general, which leads to inefficiencies

Pros

Team cares about you as a person and your growth. Huge focus on empathy, making a difference, and work/life balance.

Cons

Could have better options for lunch and snacks at the office. More structure and consistency with processes would also be helpful, but this is expected of a growing company.
