They were using the Wonderlic test....
You take the test score, double it; then add 60 -- to arrive at a decent approximation of IQ.
That's how a score of 22 became an 'IQ' of 104.
It tops out at 140 -- which would be a perfect score.
It works because it's timed -- and the questions get tougher and tougher.

As for craft smarts: they're given away by personal tools. Admittedly, it does take some smarts on the part of the interviewer to recognize whether they are poor, average, very good or outstanding tool sets.
No man treats company property better than his own tools.
As Sherlock Holmes would put it: they tell a story.
