When EZY stated at the outset:
Please only apply if you have the following minimum requirements:
With one of those requirements being:
Willing to self-sponsor type rating.
I think they made it perfectly clear what the arrangement is. Now whether that takes the form of a monthly deduction from salary or full payment in advance is not yet known, but you will be paying for your own rating.
Whilst willing to sponsor, the T&Cs will have to be right to accept a position, if offered.
So, Willing (yes), Able (yes), Going to (thats all depends)
