Some are hiring programmers: my dad tells me that anyone with a degree in computer science can find a job where he works.Sure, maybe, there's no compelling evidence either way. I don't know if the reasoning is more INTP than another or not. Going after one bit, he has the idea that employers are maybe perfectionists for candidates is because they have so many applicants, and then he targets the prescreen software. Fine idea, but nothing like that what I've ever seen, I think it's simple psychology.
Back 10 years ago we were hiring like crazy. We had stringent requirements for who'd we take, but in the end we needed bodies so the goal was to push people through the hiring system.
Now we rarely or never get to open jobs. When we do, psychologically your viewing it as a much rarer thing (there's only one), so you treat it much more carefully. Further, we're staffed much less now so you want to get somebody competent, because if you don't it will drain rather than make your job easier.
I think it is that simple, people take them more seriously because there's so few openings, so naturally people will treat them more carefully. Regardless there's way too little to go on if he's an INTP or not.
