What kind of feedback do you expect from us at the end of this experience?

If your school has a protocol for receiving performance feedback, let the interviewer know that and offer to provide it to them. You should also provide specifics about the kind of feedback you personally hope to receive. For example, you might be seeking feedback on your communication and writing skills as well as your ability to execute complex tasks.

"My school does have a specific form for evaluating my performance, and I'm happy to send that to you right away. However, I'm personally hoping to receive constructive criticism that addresses my areas for improvement. While I'm very confident in my communication and writing skills, I have less experience with developing strong calls to action, so I'd love to be mentored in that area and then receive feedback about my growth."
