Upper management and corporate seem to be in a constant power grab and undermining each other.
There is a "training course" but it doesn't prepare you for what you'll need to know. 99% of the job is memory intensive and you'll have learn and memorize as you go.
***Document everything you do and everything that's told to you by your manager and HR. They won't hesitate to lie and practice shady behaviors.***
If you're at a branch, there's very low opportunities for upward mobility much less a promotion/title change.
