As far as fellow CU students, most wouldn’t even know which college the person next to them attends. Based on what my daughter related, it truly doesn’t matter in that respect.
She might have found out eventually, when they were grouping-up for certain projects/labs - or because a word was casually dropped that someone needed to rush out to pick up a child from after-care - but again, it certainly didn’t matter.
Eventually, people bond over a class/course being a “shared pain”, rather than what college they happened to have enrolled in.
There are some classes (e.g., late afternoon) that might have a noticeably higher proportion of GS students because of their work/family schedule - but again, they are mixed-in with traditional students who despise getting up early.
Socially of course, there are differences, between on-campus students of the same age range, who will have more opportunities to connect and “hang out” together vs “commuter” students, or those of another age group. Again, not specific to GS, but just a matter of practicality/opportunity to connect.
Unfortunately, I have no insight with respect to perception for job applicants.
