Yep. Leetcode style problems are effective filters only for people who grind leetcode. It's tailored for a very particular level of developer; someone who is smart enough to understand the problems and solutions (and retain them well enough to trot them out quickly), ambitious enough to put in that level of effort to work for a 'top tier' tech company, and sufficiently docile and willing to work on BS (outside of their working hours, typically, too) that they'll spend that kind of time just to try to make it into one. So someone who went out and built a SaaS business themselves, was moderately successful, and sold it? Not going to pass. Someone who spent three months grinding leetcode and doing little else? Probably going to pass. I'm guessing it's highly effective at selecting for the kind of candidates these companies want.
