My high school used to organise a Saturday every year when they would invite their old alumni to come and tell any interested students about their academic and/or job experience. Lots of people would come, since it was a good chance to catch up and have a free quality lunch with their old friends and teachers (many of whom were friends too—it was a small, quality school).
The logistics and self-selection effect meant there was an overrepresentation of younger people who still lived in the area (usually working engineering, office, or teaching jobs), but it was still an extremely useful experience.
