A good interviewer will spot a coached candidate instantly
I'm glad this came up again, as it was brushed over earlier. A good interviewer will be able to recognise if somebody has been coached. What will their reaction be if they were to ask a candidate how they prepared for the process and were told "Well, I paid some guy to coach me". Place them next to an applicant that prepared themselves, organised their own visits to units and picked the brains of some people on this forum..............basically show initiative and perogative. I know who I would rather give the position to.
