Was hired to do a difficult job, when the job was completed the management moved me to another team, with a new manager. The new manager was/is incompetent, and cared only about hitting their personal KPI's and taking credit for any team success. They refused to listen to senior engineers advice (new manager was a mid level engineer internally promoted to management when someone else left and always knew better). All of my advice was ignored, the end result of which was massive technical debt and inefficiencies across the board. I managed to last about a year before I could take it no longer. I quit two weeks before head office canned the entire project and fired half the studio.
