From experience, this depends a lot on the airport (and maybe the shift you meet too). You might just have been flying from an airport that is 'sharper'.
I fly many times a year from different German airports to the US, and it is always easy-peasy, except MUC (Munich) - there it takes much longer, long questioning, full camera disassembly required, all electronics out and rescanned, etc. Either from bad experience or different training, MUC personnel has a very different approach.
