I share the parents attitude. My job postings though don't say explicitly that we are fine if you learn the stack, however they list the stack as nice to have rather than must have. IMO, everyone needs to learn a from of stuff for every job. Thus understanding of high-level concepts and ability to learn are paramount. If you tell me though that your primary language is XYZ and you cannot answer basic challenges with it we encounter during the interview then that's a really bad sign even if I don't care much about that actual language.
