My gut feel says there may be a small correlation but not much. I myself credit this leetcode nonsense for being able to land a job in the SW industry despite not having a CS background or any relevant experience at the time. But I found out I had vastly over-estimated my software engineering skills and that proficiency in solving puzzles does not directly translate to building good software. The real advantage in leetcode is that it is well structured and relatively straightforward to scale preparation in. Practice lots of questions from a pre-defined bin of algorithms and data structures and you're good. Assuming the candidate is actually skilled, the real killer in most interviews is if the format of the interview is new or if the interview is some sort of technical discussion and there is impedance mismatch between the interviewer and interviewee. Leetcode has no chance of this happening -> you get the optimal solution or you don't. Ultimately, the problem with leetcode is that it is a very flawed way to scale the interview process that was foisted on us by Google. Interviewing is supposed to be a human process, so any way of "scaling" it is bound to be stupid in one way or the other.
