Aptitude tests are rubbish, designed to keep HR people in a job.
I underwent the same aptitude test (the RAAF ones) three times over five or so years:
- for the "Sir Richard Williams Scholarship" to the RAAF Academy - they loved me, I won the scholarship (only 1 person per state)
- For a QANTAS level 2 scholarship - they said I had "a problem with maths" (they back-pedalled a bit when I told them I did a maths/physics double major) - but they failed me.
- For a QANTAS direct entry pilot - they were ambivalent and put me in the hold pool.
Now these were exactly the same tests - same words, same physical tests (apparently the guys who did the RAAF tests were poached by QANTAS). So - the same tests by the same person (growing in aviation knowledge and ability) with three different results.
Simply - aptitude tests are worth nothing.
