Avantages
Benefits are pretty nice - the salary for such a position is quite high. Add in game points, allowances for hardware, and so on, and it's not bad. You also get your fingers in a /lot/ of EA games, if you don't mind a support position. A huge number are supported here. Culture is mostly good - lots of employees are gamers as well, and it's easy to chat them up.
Inconvénients
However, support seems to be the limitation. There is very little opportunities to advance in any meaningful way. There is little to no help with career progression short of the occasional suggestion of an opening in the same studio. There is no progression to Senior representative or Team leader - if you're at the base Customer Service job, you're staying there unless you find another employer, or know someone in another studio in the first place. Work hours fit the customer base demands, but are rather brutal on the free time - even if you feel like doing things, you're often too tired to do so for a day.
