Interview questions [1]
Question 1
Between AON online free resource or JobTestPrep. I studied with both and I think JobTestPrep is the most similar, because it emulates the level 1, level 2, etc. screen which basically takes a second or two off you time, so you are better accustomed to the real simulation.
