I’m thinking about interviewing at a members-only lounge.

I’m not very knowledgeable about it myself, but generally speaking, I don’t think anything is compulsory. You should ask about the details during the interview or call them directly to confirm. Aspiring entertainers aren’t just beautiful—they’re educated and well-rounded too, so I imagine the competition is pretty tough. If you’re going to do it, you might as well compete in that kind of world, right? Good luck!
