I wouldn't want to be hired by a company that did this. I want to work with good people. A rigorous hiring process, uniformly applied, will tend to select good people, so it's an attractive feature of a company for me. Although i have been lucky enough to work with some good people so far, i wouldn't trust any of them to fill a company with equally good people merely by recommendation.
