The thing I don't like is that US companies take it too far, to the point they're violating my privacy and making me uncomfortable.
Why do you need to do a hard credit check before you give me an offer? Why do you need to know exactly how much I owe on my credit cards, car, house, how much I'm paying per month, and how much I've made at every job for the past 7 years?
That feels... excessive. And weird. And kind of unfair. Now you know my paycheck, and the paycheck before that, and how desperate I am. Well, there goes negotiations.
