Pros
There is training and certification programs to get expertise to use in the next job. People can be okay with the right manager. Easy going if you just want a paycheck and do what you are told. Some mentoring but it is hit and miss.
Cons
Promotions are based on a drinking social culture. German for German speakers if you want to be in the upper management. A bias against US management. Passive aggressive people as a management style. Older people not welcome. It is not a place of continuous improvement so identifying issues to make the place better will be frowned upon by colleagues who have to do work and their management. They hide problems rather than fix them. They will apologize to clients and that is it. They are behind the curve on every aspect that are important to the industry. They are just getting traction on Cloud computing. Consulting is left to the integrators ceding revenue to them and, more importantly, SAP is not learning the install problems of their own product. SAP is always following others rather than leading and will never catchup to others. Eventually, it will lose ground to competitors.
