I think a fair number of Leetcode 'medium' problems are reasonable as augmented versions of FizzBuzz. In most cases, someone who can code should at least be able to write a brute force solution to one of these problems and explain why their brute force solution is slow. Where I think Leetcode-style questions become problematic is when they're used as test of whether someone can invent and implement a clever algorithm under time pressure. Unless you're hiring someone to do specifically that, then I think this style of Leetcode interviewing is of limited value. Also, some Leetcode problems just have unnecessarily unfriendly descriptions. For example this one, which is quite simple to implement, but which has an unnecessarily obscure problem description: https://leetcode.com/problems/count-and-say/ https://leetcode.com/problems/count-and-say/
