Pros
The discount and about half the people you work with would be the only pros I can think of.
Cons
Not only is in store management an issue, but higher up management is even worse. If you're interested in working for a brand that expects you to do their advertising because let's, be serious, when is the last time you saw an AD from Buckle that wasn't their own Instagram page or an employee's Instagram page. You also might get a promising interview where you share you need to work full-time and they only schedule you about 10 to 15 hours a week. You will only get more hours by having a high sales commission day. However, if you work in a slow store, the likelihood of you selling hardly anything will be slim to none. You can then expect those hours that you had expected to receive to completely dwindle until you are no longer employed there. If there is an opening at an American Eagle and you enjoy the same type of teamwork and sales and a passion for denim, I would advise applying there.
