Looking at the history of challenging engineering programs, I'd say, "math helps, but is in itself insufficient". I think serious engineering takes way more than good math chops. And having a mathematical inclination or turn of mind doesn't automatically make someone an effective engineer. PS: My point is, Engineering should be seen a serious discipline on its own, which draws from math, science, psychology, management and a dozen other fields. No single aspect (either math or leetcode) should be emphasized as a panacea to Engineering mastery. There's no shortcut.
