Around the time of the pre-historic animals, I was a candidate for the RAF College at Cranwell. I was told to stay away from the Candidates Mess as a number of "plants" were there (not the green variety, either). It was also suggested that at least one of the Syndicate Team Members was a 'plant' as well. Geees, talk about paranoya, I got pissed in the Candidates mess every night (five in a row) and rubbished my team members as much as I could. I was one of two selected out of 60 starting on day one. Years later, I was part of the recruitment team in my airline. Dealing with hundreds of qualified applicants left us no time for clandestine activities. Actually, we would have had no interest in pursuing that line anyway. Relax chaps. Be yourself. They know what they are looking for. Good luck & enjoy.
