MM,
Colleague of mine, captain, very competent driver (>1,000h multi) with good CV and social skills had had to hang about three damn long years before he eventually got his first airline interview...
Please understand EVERY operator anywhere in the world is being inundated once word hit the street they are looking. And even without people knowing CVs keep flooding through the mailbox. A numbers game. Appreciate the game. Play the game.
Keep trying!
