Exactly, the acronyms should be viewed as tools for the interviewer, not as trivia for the interviewee to know. Asking the interviewee to explain ACID or SOLID is fine, but if they don't know the acronyms that shouldn't be an instant fail, it just means the interviewer has to put in a little more effort. The interviewer should go deeper and say "Given we're using this data to do this, which of the options of the MongoDB insert should we use?" or for SOLID, show them a piece of code and ask "What criticism do you have for this code? How would you refactor it?". Given how some people study for these interviews, you might be better off going deep either way, to avoid getting rehearsed answers on these trivia questions.
