The recent work on how SAT scores don't predict college success is similar. There is a huge amount of influence around 'fit' and environment. Some people just "click" and some people don't. Genius rock star programmers that don't click are poor employees, and some times former washouts that do click are your key hires. Hard to predict.

Things like the Stripe CTF contests are good recruiting tools, hackathons kinda sorta, resume scanning and the 5 - 10 person interview panel? Hard to get repeatable results.

What do you mean? SAT predicts GPA pretty well and it predicts it better for harder than easier subjects.

SAT predicts GPA better for high ability subjects: Implications for Spearman’s Law of Diminishing Returns Thomas Coyle,a, Anissa Snyder,a David Pillow,a and Peter Kochunovb
Abstract This research examined the predictive validity of the SAT (formerly, the Scholastic Aptitude Test) for high and low ability groups. SAT scores and college GPAs were obtained from the 1997 National Longitudinal Survey of Youth. Subjects were classified as high or low ability by g factor scores from the Armed Services Vocational Aptitude Battery. SAT correlations with GPA were higher for high than low ability subjects. SAT g loadings (i.e., SAT correlations with g) were equivalent for both groups. This is the first study to show that the predictive validity of the SAT varies for ability groups that differ in g. The results contradict a presumption, based on Spearman’s Law of Diminishing Returns, that a test’s predictive validity should be lower for high ability subjects. Further research is needed to identify factors that contribute to the predictive validity of the SAT for groups that differ in g.
