The screening is fair. There will be two captains and two people from the HR department.
They will ask you to take with you all the documents that they requested in the previos email. They are gonna check them with you personally.
Then there will be a personal interview, straightforward, no tricks, fair. Try to be yourself and explain your doubts there.
After that, you will be told your simulator session time in the afternoon.
The simulator session is widely explained in previos posts. And it is like it is, no tricks and nothing new. Then, you will wait after the simulator for half an hour or so until one of the HR representatives come to you and tell you that you have passed and give you a time for the medical next day or that you have failed and thanks you for having made the assessment with them.
Try not to celebrate anything on that day in case you pass. Beers won't make any good to you for the medical exam.
Hope that helps.
Goodluck!!!
