When I applied last time around 4 years ago, I didn't get called for an assessment for a number of weeks after they started calling the first people
I went to the assessment day and again I didn't hear anything back for a long time.....I'm thinking it was at least a month. Then I got a call out of the blue to be back in dublin for interviews with 2 captains. I was traveling from canada. I flew back to canada the next day and had a phone call to got back to dublin for the psychometric interview a few days later. I was not selected in the end however.
moral the story was there was a lot of waiting around and then it moved very rapidly towards the end.
THe process is different now so that might change things quite a bit but I just want to share my experience.
btw I applied again this year and have not been called yet, but all I know is your still in until you get that rejection mail.
