To everyone still asking about how the interview is
I passed - no surprise questions! There are several people here who wrote down all the questions they got. Should be plenty of info about what to study. Study 737, and general POF/MET! (ATPL) I am not gonna write down all the questions I got, as ALL OF THEM are in previous threads wrote by others. About the sim - they expect that you can track, fly a SID, hold and shoot a VOR/NDB/ILS.
Beside that they test CRM/MCC/ADM. Good luck!
