Aon lists the test as Working Memory (gridChallenge). It measures your ability to keep something in mind while you process other information at the same time. You complete nine tasks of varying difficulty in 9 minutes.1

Working memory is one of the modules in the Aon pilot assessments that Jet2 describes for its 2026 FlightPath cadet programme. Other employers choose their own set of tests depending on the position.12

For Aon's performance tests in general, points are usually added for each correct answer and deducted for every incorrect answer. It is normal not to complete everything in the time.1

Aon's preparation page explains each test in a short screencast video, and the test itself starts with an explanation and example exercises without a time limit. Once you start the real test you cannot interrupt it, so start when you have 9 quiet minutes.1
