Jimmy, with the whole "why do you want to be a pilot?" question then I think CTC are generally trying to get at those core parts of what being a pilot means and what stands out to you. Such as the possible different types of flying (charter, LCO, long haul), the possible career progression up through an airline, the chance to see different places, to be at the controls of cutting edge technology, to be part of a profesional team and meet new people......... and so on.
