The point, as always, is that intelligent people find other intelligent people to hire by asking questions that aren't uniform or one-size-fits-all, or which only require regurgitation of facts, but rather by probing how and why a candidate thinks a certain way.

This should be obvious by now. Standard CV reviews, colleges and references say nothing about how efficiently a candidate is able to think through new problems or how elegant their solutions will be. Nor does that mean that formal training and real-world skill exist in an inverse relationship as a lot of self-taught coders (myself included) like to pretend it does. They simply aren't co-related, at least not as far as we can tell from most leading posts about hiring on HN.

So if the goal is efficiency, why not just hire people based on their IQ? What else is there that qualifies people for positions where their bosses 2 levels up have no idea how they're actually executing the work that's put in front of them, and rely completely on them to come to the best logical solutions to new problems creatively, quickly and every single time? The only other standard you might want to look for is trustworthiness, but you can't measure that in an interview.

Anyway, it doesn't matter if someone with 140+ IQ has ever coded before. It's probably worth paying to train them. So let's just cut to the chase. You need people with brains and integrity, and the rest of it is just huff and puff nonsense from HR people who don't have a clue, and couldn't do the job their hirees do.
