Some management, especially in the department i worked in, showed preferential treatment to certain employees. Don't plan to be given any significant responsibility or management role of any kind unless you are a woman.
My boss regularly lied to you, didn't give me the chance to advance in my field, and ignored my requests as an employee for furthering my career.
Be prepared to work many many hours of overtime and comp them all because you will have several months of sitting at home and not working.
The best thing I did was leave this company and go back to my previous employer, thankfully they took me back after my lapse of reasoning made me take a job offer with this firm.
The worst thing that happened to me though was being yelled and cussed at like i was garbage by my boss, in front of another employee. Sadly he feels that this type of interaction is ok, as I have seen him do it to others as well.
