Pros

genuinely cares about you and your life inside & outside the company -> work-life balance is key. Everyone goes out for lunch - the office is dead between 12 and 1. Everyone goes to the weekly happy hour and it's super fun. There is an emphasis on the long-term goals of the company. And the company is willing to work on the hard problems and deliver higher quality product experiences - even if it will take more time and effort. The company is diverse and values diverse opinions. People are encouraged to be vulnerable, take & give feedback, and constantly improve. The company values individual growth as much as company growth and sees the two as interdependent.

Cons

It's an early-ish stage company so some processes and resources are still being developed - I think this is actually a pro disguised as a con bc you get to be a part of those decisions.
