Pros
I worked a couple years ago at YesVideo in the Call Center department. My fellow team members were wonderful people, both as co-workers and friends. It was a great stepping stone to an even better position later on in my career. I got to work directly with customers as well as with the key strategic partners - the 2 largest at the time were Costco and Walgreens.
Cons
Call center work was tedious, repetitive, and boring.
Every call center representative was vastly underpaid and rarely given raises. I'm pretty sure back in 2008-2009, every rep had a starting rate of either $10 or $11 and hour, no matter the experience they had. I remember when one person working there for probably a year and a half and being refused a raise. Another was a college student who was a part timer, and being part time was their reason for refusing her a raise. I was there for about a year and a half, and was never even discussed with about a raise. Then again, this was during the peak of the economic crisis and they could've frozen all raises.
There was no incentive to do good work. You just show up and do it, which gets boring very quickly.
