Question about college selection for undergrad and grad school

Do employers care about where you got your undergrad from? Like will an employer be more willing to hire somebody from USC over somebody from SLO?

I’m looking at USC and SLO for mechanical or aerospace engineering, and I know both schools offer great opportunities to their students, but SC has that “brand name” tied to it.

Also, I’m considering graduate school after maybe 7-10 years of employment. Is going to a reputable grad school like SC worth the investment?

Thanks.
