Hi Mlambin,
I guess you got invited then for the SXS? Not SXD?
If that is the case, then yes it should be Mollymawk.
I was at SXD Assessment. There were like 12 people. So I think for the Turkish Sunexpress will be the same, but you should take this chance. It is a good Airline to start your career. There will be always someone who could lend you this money somehow. Work hard to pass the assessment. If you pass, then you have a good job on an good Aircraft. Dont throw away this chance. No matter what, you should go for it.
You never know when you get another chance with just your F ATPL and 200 hrs.
