Pros: ergomonic phones and chairs, mostly pleasant coworkers
Cons: low pay, inconsistant hours, high stress
My typical day was on phones chasing prescriptions from annoyed doctors for furious nurses for very sick people. The hours were constantly changing, overtime was often required, and the culture was that no matter how nasty the client was you had to have a smile in your voice. It was tough.
The people there were on average pretty great. Pharmacists could get entitled and management did what they could, but techs were the peons of the company and reminded of it often.
I did learn about some billing and insurance resolution, but since the work environment was so hectic training was not a priority.
