Group interview in the back of the store with four other potential employees, all in their late teens or early twenties. We were interviewed by the store manager and another manager, answering their questions one at a time as they took notes. The dudes on each end of the semicircle of interviewees had it worst off, because they were the ones asked the questions either first (no time to think) or last (have to follow-up others' answers).
It was pretty apparent that some of the interviewees had never been in an interview. Advice: look up, speak clearly, don't ask about discounts (it's 40%, you're welcome), and smile. Make sure you're answering the questions they're asking; it was boggling how the interviewers would ask for specific answers and people would respond in generalities. Also, blatant pandering doesn't get you anywhere.
