Hey Giggey,
It takes a few days b4 anyone gets to you. Count on about 1 week max. I suggest you go and practice the SHL and the other links they give you, it'll set your mind for the psychometric test. In general, if english is your first language or close to it, you won't have any trouble with the verbal reasoning. Then the graphic reading is all about calculating the percentages (%) Practice a few of them. The other one, is the logic reasoning which is a bit trickier. What I suggest is to have a paper with you and put every sequence down on it instead of doing it in your mind because once you have combinations of actions you'll need that paper. The whole process from applying to being offered a contract was about 1 month. Hope this helps bud and cheers!
