Carmoisine nice post, summed it up nicely.
FOK.....generally you'll need two good sim checks, one could be your initial and then the following recurrent six months later. They are also looking for one season of winter operations and I think 500 hours flying FR aircraft.
But like everything here, nothing is in writing. So if you have a bad day in your second sim, or the examiner is on a power trip it will take you another 2 consecutive sims to be put forward for upgrade.
And after all that you'll probably be offered a basic salary of €56,000.
Best of luck with your assessment, if you take the plunge.
