For technical interviews I've settled down and just ask the candidate questions about things _they_ are familiar with, so things they've done recently and then try to gather how much they really understand about that, if enough seniority then also how much they contributed towards decision making.
After all I'm trying to find, do they have initiative? do they care? do they make informed choices? do they think by themselves?
