of course you guys are talking about journo internships,
but here as a part of any engineering degree summer "internships" (We call them work-experience, but the same thing really) are done as a core requisite for graduation
legally the firms are not required to pay these interns, but depending on the firm you work with, they often choose to offer "Pocket-money" to the students as an incentive to work with them...
and engineering interns are really like a 12 week mini-thesis, where the company benefits from your research, and hence you get credit for your course under "Work-experience"
