Yes. Yes, you do have questions. Some of your questions will have been answered in the normal give-and-take of conversation, but you should always be asked if you have others (and if not, something's wrong).

Having questions means you're interested. Some questions are best directed to HR, while others should be asked of managers and future co-workers. Ask questions that show an interest in the position and the long-term plans of the company. For some ideas, see "Questions You Should Ask in an Interview," below.
