Received a phone call and was asked a few upfront questions about shift availablity. Once I assured them I could work nights, they scheduled me to come in the next day. The interview was informal. I wore nice jeans heels and a light blazer. We sat at a table by the checkout line. The questions were very simple, tell us about you, why do you want to work at Whole Foods, customer service questions. Really relaxed. All the employee's were friendly, happy and it was a very pleasant experience.
