As you know, an internship helps you build skills and gain experience. But the interviewer wants to know if you are genuinely interested in an internship at this company. Use this opportunity to share the knowledge and experience you hope to take away from your time in this role, but also share why you chose this company. Perhaps they are a leader in the industry or employ the best of the best; share your reason and be sure to mention what skills you will bring to the organization. Your response will help the interviewer align your desires with the opportunities in the organization.

"This company is a leader in the XYZ industry. An internship would allow me to build on my skills and work with some of the best people in the field. I would love to be able to bring my skills into the organization and learn new ones from a reputable company like this one."
