We ask a programming question that's harder than fizz buzz but not terribly difficult. There's an opportunity to get the gist, but miss some edge cases which leads to good conversations. When I go in to discuss the solution, I ask how it went and we end up with three scenarios: 1) candidate is modest (it was pretty tricky but I think I got it) and they did a good job 2) candidate is modest (it was tough I think I screwed X up..) and they made some major mistakes 3) candidate says it was easy and totally blew it. I've yet to have a candidate who said it was a breeze actually ace it.
