Itchy Kitchin, why do it via PM, maybe other people want the info as well?
As I remember it (only a couple of months back) there was:
Maths test : Multi-choice, interpreting statistics, graphs etc and doing calculations from the statistics - calculator was supplied.
Verbal test : Multi-choice, reading paragraphs / articles and answering questions about them (sorry, can't remember the exact sort of question - I think about conclusions etc).
Psychometric test : The usual.
Interview : 2 to 1, general chat, non-technical, questions on background, training, aspirations, why channex, how do you feel about having to buy a type-rating from us, what are you like to work with, personality/CRM questions, etc.
2 weeks(ish) later if successful invited to the 737 sim.
Hope this helps, good luck
