YMMV but I'm asked for my salary expectations withing first 10 minutes of the first phone interview. Usually it's immediate "no, we don't pay this much" and process don't go any further.
Sounds like a time-saver on both sides. I don't agree to even talk to a company beyond the initial contact without some sense that there's a possible zone of agreement on compensation. Why waste my time (or theirs) on an employment discussion that can't possibly end in employment?
Being at the expected salary level where you even have input on salary already makes one more privileged than the supermajority of workers this would affect; the readers of this board are largely not who this law is for.
