Pros
Experience for entry level. Free books.
Cons
I concur with many of the other posts regarding the lack of mentorship, recognition for good work, and lack of promotion unless you are “in” with one of the higher-ups. It's all politics here; be ready to be stabbed in the back. Some general statements: as far as books go, they have moved more and more toward celebrity books and right wing politics. If you look at all the truly interesting writers and books out there – they are not at Harper. They talk and talk about the digital age. Constantly announcing new initiatives and hiring new people. But they haven't updated the website in years. They are not adapting well to the digital age. Do not expect to be treated like a professional here. If you can't play the politics, you are screwed. HR is not there to help employees, only to tow the corporate line. There are some decent people that work here. But abusive managers are accepted and often promoted. If you want to be respected for your work and as a person – do not work at HarperCollins.
