I was trying to find a source for this, and I see that it is really variable. Most sources I see are saying more like <$10k, though some go as high as "3-4x the employee's yearly salary", which is what I'd like to know more about. I don't see anyone explaining how that latter number gets so high. I assume most of the cost is the time of multiple interviewers across multiple candidates, but that still seems outrageous to me. Even 1x the employee's salary would be 4 similarly-paid colleagues doing nothing except interviewing candidates 40 hours a week for three months, which I've never seen happen. Even the most grueling interview process I've been a part of has been more like 2 hours a week for a couple months.
