What Questions Do You Have for Me?

At the conclusion of an interview, the candidate asked me what I was looking for.  After I provided my answer (which the job posting literally answered) they asked if they were the person I was looking for.  They were not!  But as the hiring manager, I decided to let HR be the "bad guy" and I told them that we had several candidates to interview and we would be following up with them.  

What is a best practice you use when asked that question? Do you think the hiring manager should answer the question or defer to HR?
