Ventajas
There is plenty of room for advancement at FS and they offer decent benefits. They encourage advancement from with-in the company. They also give you feedback after your interview to help you the next time you apply for another position. Benefits-wise I really like that I had the ability to get full benefits. They were also willing to flex the schedule to accommodate medical appointments, etc.
Desventajas
The main issue with working for a call center is that they'll hire almost anyone. This is no exception. Many of my peers weren't interested in actually doing work which is ridiculous since our job was very easy. Also, there was some disorganization within the company. I felt like no one had a long term plan in relation to my position which was not very comforting.
