Sorry for the thread hijack
I am awaiting the results from my tests and so hopefully will also be soon attending the interview stage. Like the original poster I am cacking myself over the personnel interview.
I think it would be helpful to all if all you fantastic, knowledgeable & helpful (end of ego-stroking) ATCOs would post examples of any questions you can remember being asked in the interview. I'm sure this would serve as a fantastic resource for all us wannabees.
