It looks like they've told me exactly the same as they've told you. Something about a lack of preperation. But unlike you i had none of the stuff about the different air craft and stuff to New York. mine was about flight progress strips, QNH, Flight levels etc and it was that type of stuff that got way more technical than any of the information that they sent me.
I've had one person advise me, to act dumb, and that they don't want a qualified ATC or plane spotter, and therefore will just run over everything briefly, and another person tell me to tell them everything i know about what they ask
I thought i did all right on the scenarios, it was when they started going really indepth about things.
I'm confused?
Anway, if anyone else has any info on how to act in your tecnical interview. please let me know
cheer
