Who are you?

Be honest. They are looking for your ability to communicate fluidly and in a sociable way. Treat it as talking to a professional friend that you haven't seen in a long time. Make the interview conversational. They value interpersonal skills more than any experience. They believe they can train anyone to be an excellent recruiter as long as they are trainable at the very least.
