As a cadet hopeful going to a low cost carrier you have no rights. They can charge you whatever fee the want, cause at the end of the day there could be hundreds of cpls going for it and only a few places. If they didn't interview them all you'd have a stink, if they charge you an administrative fee (which is less than the processing fees for qantas applicants mind you, not even close to it) you act as though the end of the world.
You paid to fly wherever you learnt to do it, I'm fairly certain 20000 rupee isn't an unreasonably amount.
And for those "idiots" who are paying for it, bitch all you want but at the end of the day they are at least making a sacrifice to take a step forward - but for you I suggest you wait for an airline to headhunt you. If ur so concerned about these people, start a picketline, if ur just ****ty the industry isn't the same as what ur flying school said it is before they took ur money then have a teaspoon of cement.
