So my summer time job as a go-fer in the mail room of the print shop of the USDA was really an internship?
All these years I thought it just $2.50 an hour. Maybe I should have gone to Woodstock after all.
No, internships are usually unpaid positions (paid internships are rare, but do exist) in with a skilled department that runs some aspect of the business. For example, I work as a storage engineer at a major corporation. We have two interns with us for the next couple of months who are CompSci majors at the local university. They’re learning the ins and outs of what we do, as well as spending a day or so at several other teams’ desks. When they finish, they’ll be able to put the internship on their resume as having actually worked in the IT department, and list the technologies they handled: IBM storage, Remedy ticketing system, bash scripting on actual production systems that do more than “hello world” etc.
In your case, an internship would have been working alongside the guys who ran the printing machines, or the typesetters, or similar, and it would be because you were majoring in something that might lead to a career doing those things. Since the company I work for is a food producer, we have interns in IT, but also marketing, sales, accounting, and even in the production plants.
