I think if you are a high school student and you need a first job it's a great starter. I would try to not stay longer than 6 months if you don't intend to move up in the company.
If you do intend to move up, I'd say for about 16 months and then try to spend the next year or two work at least 2 other retail stores and then return to Hollister when you have your bachelors or a month before to settle back in then apply to become a manager. make sure you're on good terms with your manager and have become acquainted with managers of other stores, they can help if you have questions. working at even one other store can improve your customer service abilities and your adaptability to different situations. you can get this same experience by staying at hollister however the lack of a change in environment can be a spirit killer.
buy their clothes, strict look policy, messy management
