It's still just as easy to cheat, because it just becomes a matter of increasing your question surface area. Hop on LeetCode, memorize the more popular questions (because inevitably companies can and do reuse questions), pretend you've never seen it before and you're golden. It's the exact same way students would cheat on a closed book exam.
Leetcode just incentivizes people to play the Leetcode game. It does not signify skill or ability or anything of the sort. It at most filters for candidates that cheat or candidates that end up particularly lucky that day.
