Pros
The benefits are very good. I had a plan with Aetna that was very affordable. At my new job, I had to opt out of their benefits as it cost way too much. The pay is also good for a call center. They will promote certain people, but many get strung along for a few months waiting for confirmation. This could be a pro if they like you.
Cons
Typical call center issues. You will be explaining to the scheduler how many minutes you were in the bathroom and trying to figure out times down to the minute. You're not allowed to give certain information over the phone, which most people don't like. Customers often get screwed into having to buy replacement equipment due to silly reasons, so it doesn't feel like an honest job. But what can you expect, most people aren't calling to tell you that you're making them happy.
