In order to work at Gamestop you need to be 16 years old. You begin the job as a Game Associate. You need to be 18 in order to be promoted to Senior Game Associate, Assistant Manager, or Manager. You receive a 15% discount off of all merchandise except new consoles. I work there myself and if you get a good store it is an extremely fun job! But be sure not to listen to GameStop haters out there.
