It's more that this is stuff you haven't used in years (because people don't write heapshort algorithms for a living) but you have been practicing and learning a ton of others (adding value to your company) that simply get eclipsed behind damned pedantic interviews.

Let me put it this way. I use 4-6 prog languages at work. On a weekly basis. But you can say that I confused the syntax for the language I wrote in the interview and fail the interview on that basis and you would be legit from your PoV. Point is -in real world- I don't need and it offers no value to remember the exact syntax between Python, Ruby, Nodejs to do this or that. The thing is I can search the syntax and have it in a sec because I know the logic behind them all. And most of actually working people I know are very busy staying sharp in what they do rather than wasting time upskiling in WB sorting algos.
