I'd agree with you, but you have to interview probably 400/500 people, all with passable resumes, just to find basic competence (let alone the skills you might really need).

What if you're talking about interviewing thousands of people, a number of which are passable on paper?

It's a search problem, not laziness.

It's not lazy and it's great for employees too.

When I change jobs, I can't schedule bazillions of 1h phone screening on top on my work time at my current company, only for the interviewer to not show up or realize they don't really have a position available. I'd rather have a one hour test from home, whenever I want.
