One thing we should note is that American companies (in America) are forbidden by law to administer IQ tests to applicants. Some try to get around this via other means, but no US company can directly ascertain a prospective employee’s Stanford-Binet (or other) score.
I took a test at a local company that was nearly identical to a standard IQ test. It was an IQ test, they just didn’t call it that. But luckily, I’m good at tests. I’m one of those that are off the charts... meaning I’m probably unstable. :)
I know at CapitalOne they used word problems in math to get around that. Flunked 29 out of 30 applicants right off the bat.
