How many candidates pass the tests?
The selection rate of a student controller recruitment campaign is about 6%. This means that we need to test 100 candidates to find 6 of them who meet our standards. Unfortunately, some of those six might not be accepted for medical reasons. Although this might sound a little discouraging, compared with selection rates for similar cognitively demanding jobs, this is not in fact particularly low. Knowing that cognitive requirements are the most important, a vast majority of applicants are tested (the ones who fulfil the basic requirements). In other kinds of competitions, the majority of applicants are eliminated at the level of the Curriculum Vitae. Only few people have the chance to be tested or interviewed.
