Pros
Probably the most thorough experience you can come by when it comes to managing and running a business. Getting your foot in the door here is pretty easy, and you will learn A LOT very fast - or drown.
Cons
Pay: It's a joke at all levels. Your salary is about 20% below market - and that will constantly be on your mind when you're on your feet all day for ~ 60 hours a week. Work/Life Balance: Doesn't exist. All your weekends and holidays go out the window when you take the offer. Expect to work around 70 hours during holidays. It seems the expectation is that the store should be the #1 priority. Vacation is looked at as a privilege that can be snatched away whenever someone feels necessary rather than something you've earned. Your personal life doesn't seem to matter here.
