Hired a lot of really standout high school grads as interns, got them trained and mentored by our senior engineers and paid for them to go on to obtain advanced education to increase their skills.
Worked out pretty good for all.
The biggest advantage was getting the kids socialized into a productive mindset with good basic job skills before the University life style ruined them for life.
Having one foot in the real tech world with real world work experience and one foot in the university academic world gave them a real interesting perspective. They did not have a lot of respect for many of their fellow classmates and even some profs.
