I think that's correct. While IQ test have some general usefulness, the history of concept of 'g' itself is based on a blank slate model where how much 'g' you have indicates how good you are a 'general intelligence' tasks. The assumption here is that the brain is like a car and g is horsepower, and the more 'g' you have the better you do at all 'general' tasks.
Except the evidence points more to the idea that the brain isn't like a general-purpose computer where G = GHz or an engine when G = Horsepower, but it's more a series of specialized units that do very specific tasks. This bit was a very contentious point for many years, between those who believe the brain is like a blank slate that has pure generalized learning ability (g) vs those who believed the brain consists of a large number of specialized units that have evolved to handle common problems.
So IQ / 'g' is a very crude measure. It's like trying to say how big your house is by measuring its height. It'll be accurate to some degree since height of the house is correlated to size, but it's going to be a poor measure overall.
Back in the heyday every workplace used IQ tests based on the promise that it would find the best people for their jobs. Almost nobody does that now. That tells you how useful IQ testing is in real-world scenarios. The main uses for IQ tests now is that you win if you fail the test tif you're a death row inmate; so exploiting a loophole in the law that says you can't execute people with low IQ (i.e. it's in there for arbitrary reasons), or if you want to join Mensa, the club for people who score highly on IQ tests. Neither of these uses actually requires IQ tests to have any sort of validity outside the test itself.

), and it's indeed lowkey interesting (when it isn't wildly time consuming and frustrating, anyway, ha). Can't imagine having someone hollering at you during the process helps any, though.
