Pros
SAP has some challenging problems to tackle and the foot-in-the-door, brand trust and recognition, and truly amazing talent to be at least considered as the vendor of choice for any company in the world. It's an exciting premise and when you're on a good team working on a promising project it's exhilarating.
Cons
SAP is one of the most political companies I've ever experienced. Major business decisions are made in the hallways or cafeteria in the headquarters in Walldorf, Germany. There is no attempt to combat the proximity bias. Meetings are overproduced stage performances, while all meaningful outcomes occur in the meeting-before-the-meeting or the meeting-after-the-meeting which contributes to confusion, lack of transparency, appearance of favoritism and sometimes ill-thought-through decisions. I'm not even to go into the deeply troubling rumors of board members cheating on their spouses with subordinates, but suffice it to say yuck; this is not mad men. Even if these rumors are untrue, rumors are only fueled if they are believable enough so that tells you something about the personal character. No one is saying that about Satya Nadella for example.
