The management is mostly incompetent. Lots of infighting, backbiting, and nepotism. You're never moving up unless you are personal friends with your bosses. They had tons of meetings, too, and never trust a business with that many meetings every day. To be fair, a few managers do work hard and care about their employees, but they are the minority.
The call volume is absolutely gargantuan. Prepare for upwards of 100 calls per day, maybe less if you have an angry caller who spends 45 minutes yelling in your ear. The management also didn't tell us until after training that they were going to put us on a sales quota and would outright fire us if we didn't match up. Nuts to that! They even tried to "motivate" us to work harder with cheap plastic trinkets.
