It depends why they didn't get it "correct" (asked ChatGPT bad, used Python REPL not so bad, used screen reader very not bad) and what "correct" even means for this problem.

There's a bizarro version of this guy who rejects people who do it in their head because they weren't told to not use an interpreter and he values them using the tools available to solve a problem. In his mind, the = is definitely part of the code, you should have double checked.

Oh. I was reading this on a phone, and didn’t realise there’s hidden equal sign (though it’s mentioned).

That does change it. In that I can see how false negatives may arise. Though, when hiring you generally care a lot more about false positives than negatives.
