Would interning through the school look as good to a potential employer as a typical internship?
This is hard to answer. Some future employers may be impressed that your university thought enough of you to hire you and some may think you were unable to secure an opportunity outside of the university. There is no way to predict how this will be interpreted. There are times when these internships are some of the best opportunities for experience that our students can get. Even so, it may not be interpreted that way by others.
