Unfortunately, "psychometric testing", is used by all major airlines and won't go away,
especially when there's hundreds of applicants available to choose from.
An applicant can meet all the requirements but if they don't achieve the necessary score,
they fall out of the race.
People that usually do well in these "psychometric testing", have higher educational qualifications,
or a naturally gifted/talented, when it comes to this type of testing.
Apart from that, half the F/O positions at Jetstar/Virgin/QF, are filled by cadets or F/O's on turboprops.
Best option is for a person to look for airline flying jobs outside of OZ, if things don't workout here.
