Here are just some interesting business etiquettes rules I found in Germany:
-NO open door policy. Knock and wait
-Germans WILL be direct and blunt
-The eldest or highest ranking person enters the room first
-At the end of a meeting, some Germans signal their approval by rapping their knuckles on the tabletop
Germany is home to some of the largest companies in the world. It is a huge hub for business.
I would love to visit to take in the business minded culture there.
