I've been with the company for years. In all honesty the best way to impress the Manager interviewing you is to be yourself, be confident in your skills and knowledge. Must love Halloween, many of the people who return year after year do so in large part to that reasoning. There tends to be a high turn over rate, while there are many people who do return there are just as many who don't. Prove to them you want to be there and that this is the job for you and you would want to return year after year. They appreciate re-hires because dedication and loyalty are important to them. Just like any other interview sell yourself and your skills. Good luck!
