No doubt it is reductive. It kind of has to be - real people are just way too high-dimensional for a single score. But it does correlate pretty strongly with success at onsites. We have a lot of hard data from the ATSes of companies that hire through us, and engineers with high scores on our assessments pass onsites at several times the rate of engineers without them (~2x onsite pass rate, ~7x total hire rate, which is a huge delta!).

Speaking as someone who doesn't like being reductive, I've had to make my peace with the fact that "flawed" can still be "way better than the status quo". And I really do think we do much, much better than the status quo of companies putting a bunch of top schools in as linkedin keywords.

If you're familiar with data science a bit - think of it as trying to project out the first couple principal components of your skills. It won't account for the whole data set, but you can go a long way with just those first couple components.
