Fount this online:
"Motor coupling alignment
pneumatic circuit design and implementation ( they give you a sequence for a set of cylinders, you have to design and build the circuit to get them to work, they'll then put a fault on your own system for you to find ).
Hydraulics along the same lines of the pneumatics, mainly checking your working safe though.
Building an air tool from a box of bits ( literally a tool stripped down to its bare components with a schematic drawing to rebuild it from then testing it to make sure it works )
Modifying an electrical circuit on paper then fault finding on the same circuit ( normally 3, simple stuff )
Motor wiring
They sometime throw in a random mechanical written test paper, most people dont know the answers unless your an ex CNC'er/ machine tooler."
Maybe what you're looking for. Maybe not. Who knows.
