What's a regular day like working in a call center environment? Any advice for making the most of it?

It tends to be very long days if the phones are not ringing, or you are not cold calling. It can also be fun talking to different people on the phone. You tend to hear some of the craziest stuff.

SGT (Join to see) A couple of things to add:
1. Be patient with the customer, for the most part. You will be cussed and told to do despicable things because of their anger.
2. Listen to what the customer has to say. Listen, listen, listen.
3. TRY to resolve the customers issue as quickly as possible. Try to become an SME as quickly as possible. These two items together can go a long way. Both with the customer and with management.

Ah, man, good question. I can't contribute, I'm afraid. All I've ever done was sail ships. I can teach you how to listen to a ship, if you like! :)
