Well the thing is, I keep hearing about these people who can't code but excel at leetcode, even that they are mass-trained in some bootcamps, but somehow I never saw one in reality and I interviewed hundreds of people. So I'm kind skeptical this is a real issue. The other way round (people who code, but can't leetcode) I agree it's an issue. Unfortunately as noted here in comments, cost of a bad hire is much much worse than cost of a no-hire, so it's the price I'm willing to pay.

I think all leetcode gives you is a proxy for IQ in the language of code. If someone excels at leetcode, they should be relatively smart and able to write code. Excellent! That’s a something, a something you can measure. Back when I was involved in hiring, it was definitely better than not having that (at junior levels). However, the idea that “IQ is all you need” is so obviously false that I think you need to reconsider. Bill Gates famously, (infamously?), hired for IQ. Microsoft used puzzles as their IQ proxy, and I think leetcode is just a modern variant. Possibly a worse version, as training has a bigger effect. Bill Gates later would claim that he overvalued intelligence. I would say that intelligence is necessary but insufficient. We would get further, faster, with a quick IQ test and then dig into the candidates experience, communication ability and personality. No need to study! The FAANG companies all have a line a mile long of candidates willing to put up with any amount of BS for a chance to work for the name and $$. If you aren’t such a company, trying to hire that game changing person for $$’s you can afford to pay is going to require a different approach.

> I keep hearing about these people who can't code but excel at leetcode I think the mass trained at bootcamp is an exaggeration. The best bootcampers are those that use it as an extended education from learning the traditional ways. I'm sure most people here complaining about leetcode can indeed spend 6 weeks there and be interview ready. But few have that time nor spare cash lying around for such a venture. And why should we need to spend thousands just to ace a quiz like it's some SAT? >cost of a bad hire is much much worse than cost of a no-hire, so it's the price I'm willing to pay. At this point I wonder. Hearing way more stories about "survivors" from layoffs burning out from jobs that keep promising that they'll hire more staff to help out with. When in reality they have a hiring freeze or are trying to offshore the work that ends up needing more time to be fixed. The stalls in a no-hire aren't just costing money in the lack of productivity, it's costing currently working employees who are doing 2,4, 8+ jobs without any meaningful increase in role/salary. It's not sustainable. You're draining a little bit of blood from a rock, but the rock is clearly starting to crumble.

No. The point is the correlation is poor between the two sets AND there's equally quantifiable things with higher correlation. If I genuinely wanted a job again all I'd do is go to one of those drilling game websites for a few nights and then say whatever the interviewer is looking for. Any test I can fail one day and pass 3 days later that is ostensibly supposed to assess whether I have skills that take 15 years to master is total bullshit.

  What you complain about is a false-negative error: an engineer with 15 years of experience can't pass these tests unless he prepares for 3 more days. That can sometimes happen, yes. The initial stated problem was different: false-positives, bad engineers practicing for 6 weeks will pass the test. That I seriously doubt is a real thing. If they managed to learn that fast, they must be good. They could be junior-good -- that's perfectly fine, you need to hire juniors too. You don't judge seniority solely based on leetcode results.
