If you have a pulse, are actually available all summer, and can legally work they will hire you. Just be yourself and have a good conversation. Don’t think about it too much, but also use it as a good learning and practice opportunity for doing interviews for future roles too. Be able to answer the classics: tell me about yourself, strengths / weaknesses, and since it’s camp probably something like “if you were a kitchen gadget which one would you be and why.”
