Most people primarily use the printed image on the pieces to look through the pile to find the correct adjacent piece of the image, and then secondarily use the shape of the piece to find the exact right spot.
For example let’s say the puzzle’s picture is a photo of a car. And say currently I’m working on a red tail light. So I’ll sort through the pile looking for pieces that are red with a plasticy-looking texture. Then after i found one I’ll look for smaller image details to find the general area within the tail light around where the piece should go. And only then do i start looking at the shape of the pieces to see where the roundy out and in bits would fit into each other.
I tried them a few times and I solved one once, but that was more by brute force and not really by solving the geometric riddle.

Is that not what you do?
