Siemens embodies a bastion of incompetence and worse still they are unbelievably smug about it! The culture BS adds to its failures and I don't think we will wait long enough to see this conglomerate break up or simply go bankrupt. The German dictators are simply all grandiose talks and no action. I worked at GBS for sometime and it was the absolute worst. @6jyj+1jFe1MkA said it right!
All in all, only work for Siemens if you don't have any other options in hand.
