Expect to be trained by people who have never worked in the position and don't have an understanding of what it entails, and expect those people to dictate the standard procedures of your position. The new upper management does not have the best interest of the company's employees in mind, and constantly renege on promises. Expect your suggestions and protests to, at best, be ignored or explained away and, at worst, earn you a reprimand. Management within the department does their best to deal with widespread incompetence and apathy. Expect a false hope of advancement - HR ignores emails and seems to prefer to hire from the outside rather than promoting from within. Expect to put up with abhorrent individuals on the phone, but also expect to talk to some who are genuinely excited about the field and want to work to succeed. Aside from the fact that you won't find better pay for a similar position in this area, those few passionate individuals are the only thing that make this position worthwhile.
