Final screening at AMS is done at the gate, where everyone/everything is re-xrayed, metal-detected and groped to TSA standards. The only time I've ever dropped my pants in public was at an AMS gate*. If you are travelling on an American airline, you will also have to answer 45 stoooopid questions. Yes, they do destination-specific screening.

However, you can have duty-free purchases delivered directly to the gate and sneak a nip or two (or twenty) during the flight. If you have ongoing connections after your flight from AMS, you will want to drink it all.

*It was an accident, I was tired, and the screener w/ the metal detector was very apologetic & probably more embarassed than I.
