This seems likely to be the case. Perhaps there is a way to design a test such that it measures how quickly one can become capable in some informal "programming language" designed specifically for said test?
Imagine an interview where the interviewer is figuring out an area where the candidate is missing some knowledge, then the interviewer goes through and helps them learn that knowledge. Concrete example might be candidate has zero experience with vuejs, so interviewer works with them to build a vuejs prototype.
