It's a 100,000-person company, so the rule is "variance is high."
I saw extremely gelled, competent, high-functioning teams working on key projects with wide impact. I also saw new teams led by inexperienced managers working on fringe / incidental initiatives or keeping the lights on on a system people knew was doomed. These experiences are not the same, though they happen at the same company.
Sounds almost too surreal to be true.
Is it really that demoralized in the management there? That's scary.
