Worst. Policy. Ever.

Talk about shooting themselves in the foot. You want a competitive disadvantage? There it is.
How about hiring the best person for the job if that person comes along, instead of deliberately rejecting skilled candidates just to hit some arbitrary diversity percentage. If you're struggling to attract a diversity range matching the demographic in your region, maybe consider why that is. But FFS don't reject perfectly good people just because you've already hit your artifically self-imposed 80% white-male-under-50 "limit".
