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.

Pros

Great office culture and teams that really believe in the Slack values! Kindness, collaboration, and craftsmanship are visible in almost every interaction you see on a daily basis. Awesome perks and a huge emphasis on a work life balance makes it a pleasure to work hard and go home at the end of the day.

Cons

Career and promotion paths are still in the process of being formalized, but good news is that this in being worked on a lot by management.
