Gamestop? Last I checked, they will have their manager (only salaried person) work every hour the store is opened, and then have the rest of the stored manned by people who, if lucky get up to 30 hours a week. Who do they hire at minimum wage? They hire individuals who are fanboys who see the store as a platform to promote their platform of choice, not listening to what people want.
In the case of myself, I ended up working a few weeks over the holidays at a local Gamestop. A manager there asked me about getting into the manager trainee program, and I said I would wait and see. After I got hired, I found out the manager was terminated for things involving bad record keeping (that is all I will say here regarding this). I used my employee discount to get an N-Gage (and some games). I then found that my seasonal job offering food samples at a Hickory Farm booth was more enjoyable than working at Gamestop so I quit. I will let you reach your conclusion on what Gamestop is like, if someone who likes videogames, and knows about them, and cares about customer interests, would rather offer food samples and pitch Hickory Farm products over working there.
