I'm very sceptical about the value of verbal and numerical testing when it comes to airline recruitment. I've completed and passed half a dozen or so of these bloody things since entering the industry. In the early days I guess it's a measuring stick when there's nothing else to go by. However, passing the Basic flight training without the ability to read, comprehend and deal with numbers would be very difficult.
The benefit of these tests dwindles with experience and for guys with a type rating and hours on type they become nothing more than another way for HR to justify their corner of the wage budget. My 2p worth anyway.
Back on topic, when I joined J2 a number of guys and girls were asked to repeat one or more of the test elements if they were Type Rated and a quick bum on a seat. My point is that these tests may not necessarily be a barrier to joining the company and this is particularly true at a time when J2 are DESPERATE for experienced, rated pilots.
