What I mean by this is say we have 2 visually identical latex CVs. Let's define 2 arbitrary measures of latex "cleanliness". We say the first CV is very clean in terms of code quality (proper formatting, reusing code, good structure). We say the second CV is very shoddily put together and although it looks the same as CV 1, it's very messy (think back to your first ventures in latex when you didn't know what you were doing).
Would these 2 CVs have different outcomes in an ATS system assuming they looked identical. My intuition says they would but I'm not sure.
