Pros

Interesting problems to solve. Smart, fun, caring coworkers. Overall the most transparent place I've worked. Focused on increasing diversity. Good perks and compensation. Feel empowered to try new things and make changes.

Cons

The company is getting quite big so sometimes getting things done can take a while (compared to a startup). Being in a remote office sometimes makes it hard to feel like part of the rest of the greater company, however, over the short time I've been here so far, it's gotten better! The review process doesn't seem consistent across engineering which can make it hard for people to all feel like they are getting and able to provide useful feedback.

Pros

- lots of challenging problems - great team - great culture - interesting tech stack

Cons

- hard to get code reviews sometimes as it's hard to determine the owner of a particular piece of functionality. - if you're not familiar with hack lang it's tough to get going

Pros

Incredible culture which fosters a team dynamic where all employees are encouraged to stay curious. Focus on embodying the mission statement and placing culture and service above all else.

Cons

Rapid growth comes with growing pains. Processes are evolving rapidly and don't always scale fast enough.
