Pros
You support variety of great products, the job itself is never boring and you can never learn enough.
Cons
Employees pay a price for mismanagement. You are judged in great part based on customer surveys and it doesn't matter, if you yourself are to be blamed for customer's dissatisfaction. Just to give you an example: when customers wait long times at the phone, they are going to complain about it, which counts to your negative stats... I saw people dismissed on this ground. The constant rotation of stuff is not going to make customers happier, as the new ones have to learn everything first. It's a vicious circle. It's very hard to get promoted, once they found a donkey to work hard for little, they will try to keep him/her in this position for ages. The level of supervision is comparable to the work camps. But maybe it's all the same in American corporations in general. Salaries are also poor, compared to others in the industry.
