@mattyglesias My co has applicants do a quantitative aptitude test which is probably pretty damn correlated with IQ but technically isn't IQ - avoids culture-specific references, more justifiably related to the actual job. We only talk to the top 20% of applicants, it is our biggest filter.
@mattyglesias I'd also point out that we are very open to nontraditional backgrounds- code academy, whatever... We do coding task interviews- as long as someone proves they can do the work, it is actually better to hire people with diverse lived experience.
