This is just my personal opinion, but if doubt they would cut the numbers so low having just asked HR type questions. I could be wrong, but if feel that the aptitude/pilapt stuff holds more weighting and by taking less than 200 people, they would be seriously limiting the pool before they even check if any of the candidates have the aptitude to be a pilot in the first place!
Again, it's just my opinion, I have no clue about the process. I just don't think that's the most rational approach.
