This is a little off topic, but we now include a simple quiz with all of our job posts. Something like: "Here's a list of people, a list of tasks and who is assigned to what task. Please define a database to store this info. Write a query that lists all of the people and their tasks. Write a query that shows all unassigned tasks." REALLY basic stuff! Embarrassingly simple! It's amazing how wonderful someone's resume looks and how awful they answer the quiz. I don't even bother looking at their resume if they can't do SIMPLE quiz.
