As an ex Board Member I remember that when dealing with older candidates you would cover the School days by asking the candidate how they would best be remembered from those days. There were standard interview question guides one of which was called the 'wrinkly card'. The wrinkly card would skip over the earlier years and concentrate on recent employment including military service where applicable. Its been about 5 years since I was there but I don't think the interview would have changed that much since.
