I recently worked for a startup where I consistently out-performed software engineers who were decades younger than me. I was often asked to finish other engineer’s assignments when they got stuck, and to find and fix difficult bugs from other teams. After several years working there, during a favorable performance review, I suggested to the director of software that I could help the company more if he would give me more authority. His response : “You are too old for me to promote”. I quit shortly after. A couple of months after I left my boss was fired, because he didn’t accomplish one task after I left.
