Perhaps there’s a difference between knowing and having internalized these concepts, versus having heard of them via a particular acronym, and being expected to remember that acronym and these specific names.

“Liskov substitution principle” for instance is something I had to look up. I can read it and say, “oh, duh, yes that’s a key part of what interfaces are even for.” I’ve built with it for decades now.

The term SOLID was apparently introduced in 2004. It would be a shame to reject good programmers who can opine intelligently on these principles, but who have not internalized this particular jargon.
