Yes, it is not, but it should be. And not "the priority" of the organization, which is, as you said, making money, but one of the priorities. In fact, using the double KPI method, "finding great candidates and treating all with basic respect" should be the guiding light/mantra/KPI of any recruiting team.

"Scaling recruiting is hard". Sure, plenty of things are hard when scaling, but calling back candidates after multiple rounds of interviews (just to highlight one common complaint) is not. That is a cultural problem.
