Pros

Good culture, great product, strong sense of ownership at all levels

Cons

Senior leadership has not found their rhythm. CEO calls pretty much all the shots. Engineering leadership is often invisible and lacks a cohesive tech strategy. Tech debt runs incredibly hot at this company and it often takes a major outage (did I mention CEO frequently joins the war rooms?) to get anything prioritized.
