What does grinding leetcode mean here? The way you prepare is important. A focused approach yields more learning. Math is typically taught in a focused approach that builds on itself. Random leetcode grinding does not build on itself. But non random leetcode grind where you focus on specific topics can yield an underlying intuition similar to the one you would gain from a math first background. I would argue that in the vast majority of cases, this approach has a better ROI of your time. Interviewers seeking to "expose you" with math tricks are probably not people you want to be working with.
