I was actually a Store Manager for that company for a year until about a month ago, and there are some really awesome things about working for them, and some not so awesome.
Awesome:
-great entry-level apparel experience, even if its at the retail level
-ability to move up quickly in company if you have good work ethic; I was an MIT for 1.5 months, had my own store in 4 months.
-young, FUN environment, flexible hours
-cool discount
-pays pretty well for retail management
Not so awesome:
-common things associated with retail: working nights and weekends, some late hours
-promotion may require relocation and some commuting
The job is really great if it fits your personality. I don't know if you have made a decision about this yet, but don't be afraid to ask the district manager or any store manager lots of questions about the company and the job itself. If you are worried about the "poser" image, don't be because the fact of the matter is that the umbrella company is a multi-billion dollar corporation for a reason. They really do have a unique product and a unique marketing technique that makes them so succesful.
I think the most important thing to remember is you would be gaining experience in PEOPLE MANAGEMENT with the apparel industry. So, if other kinds of management interest you then it is perfect. They also have a Visual Assistant Manager position once you finish training, that you could use as direct experience for merchandising. I hope I helped! Good luck!
