I was able to find those things but I fail to see how they are relevant. My point is the IQ test are in contrast to leetcode tests because the IQ test is transparent and transferable between organizations. These tests are neither transparent nor transferrable. Aptitude tests like this have been safe from disparate impact lawsuits for a long time but not for any legal basis. My point is that while such aptitude test leaves them less exposed than IQ tests it does not eliminate it. That they haven’t been sued yet isn’t evidence of lack of legal exposure.
