Is there a word to describe this no-hire tactic?

I am wondering if there is an established term for when a candidate, following the technical interview, is not hired to a position with the explanation by the hiring manager that the candidate did not show experience with 'XYZ' when the position description does not mention 'XYZ' as a required or preferred qualification. In sofware dev. this might play out in the following HYPOTHETICAL SITUATION >> candidate applies to position listing experience with web front end frameworks as a required qualification, with React and Vue as preferred qualifications. After the technical interview the hiring manager explains a no-hire decision because the candidate did not demonstrate proficiency in CSS. Is there an established term for this?
