Yeah, I recall we had interns. I was asked if I wanted one for a summer a few times, I always said no. My friends who had them regretted their decisions.
But there could be the rare intern who would make a splash. I know this is very common with engineers, a requirement most places. Anyway, our company required the piece of paper. I was offered the job before I graduated, as is common, but it was contingent on getting the piece of paper.
