"I hope HR depts get the memo on that because they have a habit of classifying people who know what they don't know as weak candidates"
Except for HR people themselves, of course: it's fine if they know nothing about the job in question, they can still filter out candidates that don't tick arbitrary boxes.
More seriously - Rumsfeld got stick for his "known knowns" thing (wasn't that a NASA thing originally?), but I'd suggest that the ability / willingness to admit there are things you don't know, and even that there might be things you don't know that you dont know, is a fairly good characteristic ?
