I usually enter Schengen through FRA or MUC and occasionally CDG - 90% of the time they do not ask me anything at all, just stamp the passport. If they do ask questions, it's a few simple ones (e.g., purpose of travel and length of stay). As a matter of fact, it is hard even to squeeze "Hallo" from German bundespolizeien at the passport control. It is my long-time dream that our own CBP will be like that one day...
