There is a lot of scientific support for pre-employment screening (selection). The most conclusive evidence comes from a series of absolutely enormous studies conducted by the US military in the 80's known as project A.
That being said, there is a great deal of pseudo science being gobbled up by organizations because this is a mostly unregulated industry.
IIRC, the outcome of these studies were that intelligence is the best predictor of job performance. The ASVAB is essentially an IQ test with some domain knowledge questions sprinkled in.
