Hi Chris, I hired a chef this way. I'd interviewed him, the owner interviewed him and then I asked him to come in again. I just asked him to make a dish from what ever he could find in the walkin. He'd never worked in our kitchen before. He came out 45 minutes later with an awesome dish and a great presentation. I don't know how common it is, but it's worth it to get a good read on someone. Cheers
