alt Hacker Newsdisagree. nobody has a monopoly on what metric makes someone good. I don't understand all this leet code optimization. actually i do understand it, but it's a game that will attract game optimizers.
the hot take is, there are other games.

This is explicitly not Leetcode, in fact its goal is to attract optimizers
Also leetcode does not really provide insight into ones ability to design business solutions. Whether it be system design, just some small feature implementation or communication skills within a team. Its just optimizers jerking each other off on some cryptic problems 99.999999999% of developers will never see in real life. Maybe it would've been useful like 30 years ago, but all commonly used languages have all these fancy algorithms baked into their stdlib, why would I ever have to implement them myself?
This is the opposite of leet code.
Yes, this applies to some simulated imaginary CPU with an artificial problem. Except that the job asked here is exactly the core of what a performance engineer will do at anthropic: optimize kernels for their fleet of GPUs. Is it simplified? Yes! (e.g. the simulator does not restrict memory access patterns)
This is a real-world problem adapted to a lab setting that can fit in one's head in a matter of hours. Leetcode would have you reimplement the hashmap used in there.
