Don't want to burst your bubble, but I know of 4 other Turkish companies paying around 6000-6250€ a month for contractors, sometimes only on 6mth contracts.
Regretably therefore, that is a "normal" figure these days, although I believe Sun Express used to pay a whole lot better in the past.
What is odd about this is that the job was advertised several months ago and it is difficult to believe in the current situation they were short of applicants.
At the bottom of this page you will sometimes see a banner ad for the DLR tests (which of course you have to pay for

) Sun Express featured quite a while ago, but not now.
Wouldn't surprise me if this wasn't just a ploy to get some cash flowing through the organisation that undertakes those tests (ATTC), otherwise why are they recruiting a second time in about 2 - 3 mths ?
Cynical ? me ?
