I downvoted you because it's unreasonable to expect people to memorize something they use once a year. Learn it, understand it, then look it up again when you need it. Interviews should reflect the experience and knowledge you expect a candidate to use on a regular basis. Asking comp sci questions they don't need to know to do their job biases your hiring process to new grads rather than experienced industry veterans.
