When I interviewed candidates I asked them to drill down with a little more detail. And after that response, if I did not get a sense they were pounding their head on a wall, I’d ask them to drill down another level. At some point, I was looking for them to walk me thru some incredible complexity that really challenged them. I’d expect them to be able to explain it, as they should if they experienced it first hand.
