That’s a great question. I think it was a gallows humor term to describe a certain level of unduly arbitrary failures in training, and the upshot being that a training failure would de facto freeze someone into that regional franchise. I’m not saying it was/is an actual program, just that I’ve heard rumblings. My involvement wasn’t to adjudicate why there are warts on a training record and whether they were correct or not. I do know that owning mistakes, and (much more importantly) taking lessons from those mistakes to get better is an important component to overcoming them in future interviews.
