Unethical practices and politicing is the norm.
Pros
Outstanding benefits - I have not come across a company since with better benefits. There are also a lot of good people in the organization, but...
Cons
Leadership positions involve extensive amounts of politicing and backstabbing. Management is asked to lie to employees to cover up wrong doings. Worse, management is told to lie to clients about significant issues (like costs). Who you know gets you ahead, not what you know. Extensive travel is required to get ahead (so forget about work-life balance if you want to move up in the company). It is a culture of "what have you done for me lately". I have seen many managers become physically, mentally, or emotionally shattered in this high pace organization only to have senior leadership cast them aside. You know you are in a bad place when you have to have a meeting to discuss how you are going to manipulate your way through layers of management to accomplish a task. "Tell this person this, but don't tell this person that" or "we'll get so-and-so to side with us against this person so we have more power". Those are the meetings and it is sad that rather than focus on organization success, the focus is more on protecting your territory or trying to destroy someone elses.
