Of course get to know the candidate as much as possible before hiring, but if you had to pick your candidate based on a single number, you truly don't think IQ isn't way up there as one of the more usefully discriminating ones?

I don't think anyone can doubt that it's likely to be predictive of success. There are sheafs of papers on that: e.g. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4557354/, though that paper also discusses confounding factors. My bigger worry is that I can't imagine any of our candidates assenting to an IQ test (outside of Scandinavia where it sounds like it's the norm).

Absolutely not.

(And I would refuse to pick a candidate based on one number. No good can come of this.)
