I've never run into this as a hirer. I don't test to see if a candidate can implement an algorithm from memory. In my test, I describe the steps for the algorithm and see if they can "follow the spec". I find most candidates (even seniors) can't, they can't help but make it 'more complicated than the spec asks for'.

Neither do I. I want to see how they work through the problem, focusing on the problem. The IDE takes their focus away in my experience, they start correcting the squiqlies and adding extra bits of syntax that don't matter in a pseudo-code setting (such as adding closing brackets they forgot earlier) to avoid auto-spacing issues and so on.
