high school internship opportunities?

I'd highly suggest Microsoft's High School Internship but applications are closed for the current wave of interns, try cold-calling local SMEs (Small to Medium Enterprises) to ask about potential internship openings. Another option would be that you start your own business during the last few years of high-school and your college years.

So my high school is in city with a population of around about 500k borderline top 50 in population. There is an organization called intern-city name that connects high school students to paid internships your city may have something like that. Or if you have connections to an organization such as family friend your family you might be able to get an internship there as big companies will usually accept more family connections or you could volunteer at your parents company.

Though jobs especially if you get a supervisor role eventually it could be weighed the same as an internship
