My Aon experience:

Cut-e prep was good, they only had me do spatial orientation (NDB), deductive logical thinking (sudoku shapes), multitasking (maths, shapes, airplane), ATC recordings, work behavior (personality assessment). Personally I felt like I probably performed average. I believe I got incorrect answers on all of them except the ATC recordings. Highest instances of incorrect on multi-tasking which I hope is expected haha. Trying now to forecast the results, but no joy, I cant control what happens now. I got the assessment invite 3 days after receiving the first "Aon eligible" email. Availability listen in application is 2 weeks notice. YMMV and god speed to all of us haha
