Pros

Coworkers and managers are mostly great Helpful team Cool product Good PTO Decent work life balance

Cons

Senior leadership is a bit messy, no clear direction on business strategy Not a lot of good communication from the top down Will make decisions out of the blue that affect you with little to no explanation Not a lot of growth opp, see a lot of folks stay lower level who work super hard not get rewarded or promoted often
