Where do you draw the line then? You can google and stack-overflow answers to pretty much any technical interview question that has a non-subjective answer.<p>BFS is not much more than a loop, a queue and a set to keep track of state (which nodes to visit next and which nodes have been visited). I can&#x27;t think of many algorithms simpler than that to ask outside of things like fizz-buzz.<p>If you are arguing for whether algorithms are an effective way to gauge a candidate&#x27;s skill then you should state that.
