Yea SunExpress is excellent to work for but i failed with a very small marigin on the DLR-test (so did 4 of the 5 other candidates i attended the assessment together with). I will pass it next time I'm sure but there's a 12 month "probation" time before i can do it again so I'm looking elsewhere meanwhile.
TK and SXS seems to be regarded as the best airlines in Turkey to work for but PGS doesn't seem very bad either. My only worries is that they will sell me a TR and then show me the door. Do you have to pay for the line training aswell at Pegasus?
