It's a symptom of how broken Google's internal culture is. It can become clear REALLY fast if you're on a dead-end project that'll never result in a promotion.

It's a symptom of how broken Google's internal culture is. It can become clear REALLY fast if you're on a dead-end project that'll never result in a promotion. A lot of the time, it's because the project isn't some new and shiny thing getting pushed by a director. Lots of critical, difficult tasks don't get attention - which means that new engineers get saddled with them, realize they've been fucked out of a quick promo, and then leave for greener (on multiple levels) pastures where they'll be better appreciated.
