They will gaslight you, haze you, and steal your life savings. Also they'll force you to bake one of 7 different types of pies. If you fail at baking the Pecan one they will immediately summon a demon to torment you.
It will be the same as every other orientation at any job.
They'll show you some videos, have you fill out a bunch of paperwork, walk you around, tell you how great it is to work there, then send you on your way before letting you come back and then working you as hard as feasibly possible without you dying from physical exhaustion. When you quit, they'll hire another guy and he'll go to orientation while you come join us here in exile.
