Knowledge and skill are two different things. Sometimes interviewers test that you know how to do something, when in practice it's irrelevant if you A) know how to retrieve that knowledge and B) know when to retrieve it.

There is foundational knowledge you must have memorized through a combination of education and experience to be a software developer. The standard must be higher than "can use google and cut and paste." The answer can't always be - "I don't need to be able to recall that on command, I can google/chatgpt that when I end up needing it." Would you go to a surgeon who says "I don't need to know exactly where the spleen is, I can simply google it during surgery."
