You see some of this if you go through "entry-level" MOOCs at elite schools, especially in topics like computer science. As a refresher I took MIT's Intro to CS and Algorithms or whatever it was called. I would have been utterly lost had I not already known Python reasonably well.
That's probably less true in some other majors; there likely no real expectation you've taken shop classes for mechanical engineering. On the other hand, you'll maybe also graduate without knowing a lot of the ins and outs of designing and building a piping system.
