Well the tests do last about 4 hours from start to finish.
These will include Mechanical Comp. (cogs, beams etc..), verbal comp. (hot is to cold as wet is to...), spatial reasonoing (3 shapes in a line and then 4 or 5 versions put together in different forms), numerical tests (5.99+16.02 or 3338+1xxx=4449 or 1/4+1/3= usual stuff).
I know a few who have not got through and am ringing them in the next few days, but will pass on any info that I can.
Order the CD "how2become" psycometric testing off of their web site. Quite good.
Then there will be the personlity questions....usually 1hr (I failed the Jet2 last month so I have a hate for HR cr#p).
Not a day that I am looking forward to really.
