Agree, if you are going to pay for a rating, do one where you get to fly. BUT, if you already have a 767 rating, limited experience and no job, surely this is an opportunity to get that first step on the ladder.
I understand that they are only interviewing those with a rating, therefore the discussion about whether or not to pay is irrelevant.
It also does not matter what the future of the company is, because some experience and salary is better than none.
