an inept manager, the nonsensical tasks, the sheer inability to get any resources, the butting heads with hoardy other teams, and the best part, the manager’s brain-numbingly boring meetings where she simply read from her own badly made powerpoints that put me to sleep.

That sounds like it could be just about any job, but it's the opposite of what I've experienced in civil service. I'm glad you found someplace you like better!
