Management sets unrealistic goals for production, forcing you to work an obscene amount of unpaid overtime hours.
While a joking environment is advertised, it's mostly the rest of the staff making jokes about other people (sometimes at the expense of other employees), and they're quick to pull the "boss" card if you joke back and strike a nerve.
There are few organic hires in the office, and it's easy to feel like an outsider. This is a group of twenty-somethings who buy expensive clothing and mock those without their fortune. They are the stereotype of spoiled Naperville kids.
Those who don't fit in with the other people in the office are forced out regardless of their work qualify and ethic. They will set you up to fail so you can quit or be fired.
Criticism is not given in a constructive manner. Instead of being sat down and talked to about areas where you need to improve, you're degraded in front of the entire office.
