It was a really easy interview. The fact that it was a group interview made it pretty relaxing. Also, it's a company that generally won't turn you down. Half the time is spent asking everyone general questions about themselves, and the rest of the time, the interviewer discusses the company's image and how you'll be expected to uphold it. The job doesn't necessarily require much intellect, so chances are you won't be the dumbest person in your interview group, and you have nothing to worry about besides how you look.
