I think it gets harder to remember exact syntax details the more experience you have and the more you have worked with different (but very similar) programming languages. I get what OP means: if you have worked with Ruby, JS, Python, Go, PHP, Kotlin, etc., you can easily misremember things like the order of parameters for a given function, whether if conditions require parenthesis, to use {} or [] for maps, etc.

If you have just started your career and are full invested in 1 or 2 programming languages, sure this may sound alien to you.

I get it. I've done a ton of languages too. But, like, that's so ridiculously easy to handle in an interview, right? "I think it's like this [show example], but maybe the hash rocket style is Ruby and it's actually colons. Either way, you get the idea."

If your interviewer finds that problematic, well, that's on them.
