No joke, when we do interviews we have candidates give code review feedback. One of the pieces of code is a poorly written but functional “find the unique numbers” function. We have had ONE candidate say, “Just throw them in a set.” And in our separate chat where we discuss candidates, we were like, “Finally someone gave the right answer.”

(Not that there’s a wrong answer when code reviewing like this, but I was waiting for someone to come to that solution.)
