Absolutely. I think about this as, one of the things we communicate with our speech is our confidence. (Likelihood that some claim we make is correct). Speaking confidently about something you don’t know is epistemic lying. And seeing a candidate lie to me is a red flag in an interview. It’s also really stupid. An interviewer wouldn’t ask a question like this unless they knew what every line of code shown does. By all means say “I think this does X, but I’m not sure”. But if you boldly tell me it does X when I know for a fact you’re wrong, that will go badly for you.
