I half agree. I know people who have a natural curiosity of algos & DS - most predictably, people who did algo/ds competitions/competitive programming. To them, leetcode is easy shit, and just naturally so. E.g. I had a group of friends who would ace Advent of Code every year while I muddled through (and always get stuck on day 7 or 10).

So I think leetcode interviews get both those groups - the ones you mentioned, who work hard and study (and thus demonstrate good qualities of being employees), _or_ those who are so good at this stuff that leetcode won't even make them sweat.
