i'm not sure i would have taken the job if i had been successful through the process, but the part of the process i failed at repeatedly when i went through the government hiring process about 15 years ago (when i first graduated from university) was what they call the "situational judgement" test. this is a test about how you react in conflicts at work; it's a social skills evaluation. and, you just have to pass it....
i failed this government social skills test not once, not twice but three times. so, i aced the iq test, but i could not pass the social skills tests, and you can't move forward unless you do.
see, and i was just baffled by it, on top of it. i just found it utterly mystifying. after the second fail, i went through practice tests, and it just didn't make the slightest sense to me - i just got it wrong over and over and over. and, the thing is that i was never able to understand why i was getting these questions wrong, or what the right answers were. you could give me the right answer, and i wouldn't understand it.
i went back to school in 2008, but i basically gave up on employment at that point. it just became clear to me that i was a fish out of water in the business or government worlds, and i'd have to figure something else out.
i expect it'd just be worse now than it was then - i don't get them, and they don't get me and it's better if we leave it at that.
