My undergraduate was in engineering and it’s fun to look back because we used to do that with business and sales. For a student org we once sold shirts that said “friends don’t let friends become business majors”... which was fun and in jest of course.

I didn’t experience a lot of what you described in my MBA program as an engineer, though. Usually it was the opposite, but I think that comes with the maturity of the program I was in where you knew that not only was engineering important and valuable, but so were sales, accounting, nursing, and all sorts of other disciplines.
