If you can make it long enough, you're untouchable.
A typical day of work consisted of showing up, getting immediately on the phones, being berated by customers -- many of which are too afraid to go to the store in person because they won't treat someone that way to their face. Then you get berated by your manager for not being good enough at customer service because you got berated by customers.
I didn't learn too much, other than that I would really, really rather not work here again.
Management is awful. The supervisors they pick are not picked on merit, but rather favoritism well beyond what I've experienced anywhere.
My coworkers were wonderful. There was not a single person I didn't get along with,and fantastically so. However, most of your coworkers will be high school rejects who refuse to continue on to college, recent college grads waiting to get something better, or older folks who need something to do (particularly stay-at-home moms with no children at home and a lack of marketable skills).
The hardest part of your job will be meeting all the insane metrics they ask you to meet if you're a phone agent. As a third-party vendor with little to no power to do anything to an account, you're going to get yelled at constantly and get bad metrics. Hopefully you're in a month where your call times matter most, because then being rude is tolerated and even encouraged if your call time is within range.
The most enjoyable part of my job was every day at the end of my shift, when I clicked "log off", and threw my headset at the monitor and walked away.
But, my summary stands. If you can make it a year without needing any time off at all, you'll be untouchable because you'll have made them about four times as much as they've paid you.
And yes, by any time at all, I mean, "even if you're at month 11 and you're sick with pneumonia but they want you to come into the call center and take eight hours worth of calls and get everyone else sick because phone calls".
