I think it's common to hear about companies with crazy hiring practices, or most companies copying the big tech companies in terms of what questions are asked.

If companies want the most qualified people, and the current state of things isn't the best strategy, does that make sense with how hiring practices don't seem to have changed significantly for a while?

I was wondering if people have heard of companies doings things like:

Identifying which questions asked are good predictors of how an employee does at 90 days/1 year.

Estimating how important each step of the interview process is, etc.
