Sure, but turnover has a strong effect on employee morale and the company’s reputation

So even if it surfaced the best candidates, hiring anyone that applied and then firing 90% of them after a week would result in a depressing work environment and an ever shrinking pool of qualified candidates (who wants to upend their life to take a job they only have a 10% chance of keeping?). Not to mention the cost of onboarding.

This is how we get to the status quo: do as much filtering as you can before you hire.
