Avantages
Good compensation, good benefits, good training and, great co-workers. I grew a lot in this position and learned a number of skills. I had a number of opportunities to participate in projects not related directly to my job but beneficial to the team.
Inconvénients
It's stressful working with frustrated or angry customers whose only goal is to vent. This isn't so bad during off periods but during season you really need more of a break. There's also a tendency for a new project or process to be picked up and then discarded within months. It's still a large company and people are not always treated uniquely. Depending on your department, you could get dinged for unexpected absences (such as illness), even if you called in every time. They are, however, more generous than some companies in this regard.
