The company is extremely hierarchical and permeated by a lack of accountability. I have seen completely incompetent managers (and higher) getting promoted or, at the very least, tolerated for years. Instead of feedback loops, there are constant political games. Decision making is hampered by tight control of information flows by leaders.
The company is also very wasteful and inefficient, throwing huge amounts of money at projects that are then not properly managed and fail, causing internal frustration and customer dissatisfaction.
There are many problems that could be solved if management paid attention and cared. Instead, the labyrinthine management structure and constant reorgs make a lot of things fall through the cracks. At the end of the day, customers suffer.
Finally, once in management, there are no real means to advance one's career. Nearly all important positions are filled without any competition.
