Evenin' folks. Gonna say thanks for all the info in this thread.
I'm doing my 3rd stage in 4 days, slightly freaking out as it was the interview that got me last year (though that was stage 2, before they switched to the FEAST system, though I've done that before when I applied to Eurocontrol, didn't reach the interview because I was apparently too 'cocky')
I'm working on my answers to the interview to show off my aptitude for the position, as well as trying to get myself in the right mindset for the Team Exercise.
I'll have to hope that all I've done over the past year has made me better prepared to do this the second time around.
Any extra advice anyone can give me would be more than welcome, and I'm also able to give advice about Stages 1 & 2 if people want them.
