Hi there,
I have had a success with one charter airline in the UK but turned it down. From my experience they take on first impressions, not necessarily experience. If you have been for a lot of interviews in the past this is the one where you have to look good. They are only hiring short term and they dont seem to waste time looking into people, first impressions count. My advice, although you may think it is only a charter airline, look good, be professional and dont be too "out there". Because the work is extremely arduous they want people who can deal with, how can I say, "not the regular passenger". Have fun, yes, but it's hard work.
By the way can someone PLEASE explain the meaning behind the maths test they all seem to do. I just dont get it?
Good luck.
