There should be a mechanism for feedback on past supervisors and managers. Many are simply not doing their jobs and are unqualified to have people responsibilities.
My managers over the past 3 years are cr---y. They have taken no interest in my career. No attempt to line up skills with interest and business needs. Felt like they shoved me into jobs randomly. They have not manage workload or advocate for me during assessment. Training has been none existent.
One particularly toxic manager inserted himself in my project when it started to have traction. Circumvented and undermined me to get a promotion for himself. Blatantly claiming credit for my work. Another had me taken off a project so her buddy can get the role I was most qualified for. (Her buddy never did any work related to the topic.) One manager didn’t bother to schedule regular meeting with the team during COVID. He went MIA, barely talk to us as he spend all his time brown nosing.
If anyone is considering this place, tell them to stay away. This is not a place to grow a career. Good managers are few and far between.
