I honestly believe the great reviews on here are bots - Graduate Engineer (Entry-level Technical Job) Duolingo Employee Review

Mission, smart and kind people, great work, hard working teams focused on results and delivering against an awesome mission. People push themselves and each other to learn and grow. Swarms of smart and creative problem solvers.

Small number of people are unhappy and instead of leaving they complain. A lot. I think it's like this everywhere but in a smaller company you feel it.

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

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.
