When designing a hiring process one should consider the balance between false positives and false negatives, and the cost of the process. Obviously we all want to hire talent and reject duds. A cheap quick process runs the risk of false positives: hiring duds. An expensive lengthy process tying up lots of top staff will eliminate the false positives, but at cost. So to reduce cost filters are introduced: online tests, homework, phone calls rather than face to face. And the filters increase the risk of false negatives - rejecting real talent.
