Aptitude tests measure how quick it takes you to realise things. The quicker you realise things, the more intelligent you are.
The only way of mesuring how you will preform under a stressful situation is through time constrained aptitude tests.
So the best people at preforming under stressful situations and acting in a well thought out intelligent manner were selected.
Stop acting like a spoilt child and grow up-your competing against everyone else and everyone was in the same situation. You were'nt as good as everyone else-it's not Etihads fault.
