During our college tours, all but one tour guides were non-science/engineering majors and mostly female. (exception being at RPI) Applying stereotypes, I can imagine engineering major students generally won’t be interested in giving general tours to strangers.
Although all tour guides were nice and gave very good tours, DS found tour guides unrelatable and was turned off.
One male guide remarked he is not computer-savvy and talked at length about their IT support and how helpful IT department is (DS was probably thinking, if you cannot build your own PC, I’m not talking to you.)
The male guides at two LACs (one was Dance major) were leaders of LGBQT associations and DS was turned off.
I think that forgoing the general tour/Info session and visiting one of the STEM major department (if any, even biology) would have left better impressions.
