It wouldn't happen if it weren't economically wise. Contrary to claims to the contrary there is no shortage of adequately qualified candidates and an endless and growing sea of unqualified. So randomly rejecting the majority of qualified candidates is a relatively small price since the hiring goal is to get rid of the vast sea of unqualified. If there were indeed a shortage the practice would be reversed and companies would be willing to risk hiring unqualified workers in order never to miss the one candidate who can do the job. But so long as there is a flood of less qualified workers along side a good number of skilled ones, the practice will continue or worsen.
