Yes, for some reason if you go to the Stanford page on CC, you never see people say that Stanford’s calendar puts them at a disadvantage for getting desirable internships. Things are different with the University of Chicago, and people say things like that all the time.
I’m not going to say it has never been a problem for anyone in the history of the world, but I don’t think it has been a big problem for a lot of people. Something’s lost and something’s gained in living every day. It doesn’t keep Chicago graduates (or Stanford graduates) from succeeding.
