Do you have any questions for me?

"Yes. Can you tell me about the other team members I will be working with? What are their roles? Also, will there be an opportunity for me to be exposed to other areas in the organization? I'm willing to help out wherever I can."

Avoid asking any questions you could have easily answered on your own by performing your research in advance. Go above and beyond in preparing for your interview and write down any questions you can think of as you research the company. Throughout the interview, some of your questions will be answered before you get to this question, and that's fine. All the more reason, however, is to take note of what you learn to ensure your questions are poignant, relevant, and unique. This will show them you're interested in the position and fully engaged in the interview process.
