has anybody ever worked for a call center?

i just put in an application for a call center in my hometown, starting pay is $2 more an hour than what i currently make and this is closer to home. it also has a more flexible schedule, and unlike my current job i wouldn’t spend all day on my feet. i was just wondering if anyone has ever worked for a call center before? what was the dress code like? what was the work like. everyone keeps telling me that i’m going to hate it there and i’m worried but i hate my current job so i keep defending by saying that at least i would hate my job for an extra $2 an hour, lol. just anybody with knowledge on call centers care to tell me more about what it’s like?
