Pros
Great Benefits, especially as you stay on. People are friendly and helpful. There are a lot of opportunities outside of the current position you have. People are very loyal and generations stay on and work there. 9/80 work schedule is really great from a work-life balance perspective.
Kontras
People move up or on after only a couple of years at a position, meaning no one really talks a long-term vision of any "department". There is no clear delineation on who owns what from a Business Unit/Central Team perspective, leading to a lot of duplicate work being done and a lot of people feeling like their toes are being stepped on. In general, processes (specifically in IT) don't change, even though there is no evidence that the current processes work. IT is viewed as a 2nd class citizen by the business. But, the view is warranted as IT is not adapting quickly to more agile development methodologies and takes a long time produce deliverables. Typical big-company issues.
