Quiet but constant.
Pros: friendly, helpful environment with good support (and benefits!)
Cons: the days could sometimes feel long, and cold-calling people is never pleasant.
The work was fairly steady, we rarely had days where we weren't busy. On the off day that we weren't our supervisors would often have us helping the other divisions. A usual day entailed going down the list of cases, calling people up and making sure our information was correct.
It was a nice, quiet work environment and I genuinely liked everyone on my team. The hardest part was adjusting to the frequent changes in policy or procedure. They didn't change day to day, but often enough that we'd have to re-evaluate how we approached things and adjust accordingly.
I'd say the best part of the job was definitely the flexible hours - you could elect to put in extra time each day to get more time off later, which worked great for my schedule.
