I would talk about candidates experience, try to find some project he/she are proud of and dive deeper. I might ask to write some code, but it is not going to be CS exam and it will be in real IDE. I might ask a design question. At the end of the day I need to answer 1 main question: "are you passionate about what you do or it is just 9-5 work"? Cause if you are you will be able to learn new things, and if you don't - knowledge of merge sort not going to save you.
