Pros

Really smart people, fun to work and collaborate with other teams which happens a lot because everyone is building rigorously. The benefits are top tier, and the company has seen explosive growth. Exec team is very approachable and in the day to day, a lot of face time with them.

Cons

Can be noisy with all the growth and production going on right next to admin employees, but it's better than not having a thriving company.
