Interns - they're like real people, but not quite.
Interns are pseudo-people, citizens of some kind still in the process of becoming a real, productive employees. They're often used for boring, dangerous, routine, or otherwise unpleasant tasks that people with actual incomes would rather not do. And interns, having no income and no power, have very little to say in the matter - in their quest to be the ones that become employees, no deed is too dirty, no task too foul. When they're not working, they're all but invisible to Megacorpolis at large, safely ignored by everyone.
Interns are spawned from the various schools and work-experience programs across Megacorpolis, either in the form of the young, hopeful who haven't had their souls crushed out of them yet, or older citizens recovering from unemployment (who have). There are even internship-prep schools known as intern-mills, where would-be-interns are specifically tutored in the hard-scrabble 6 months that await them.
Legions of them toil every day in Megacorpolis with the hope of ascension to real employees and an actual paycheck. Until then, they'll have to make do with whatever scraps are left in the breakroom and "experience/exposure." It's a great opportunity, you'd be a fool to pass it up, or so they say.
