I do notice though that the 'culture' of universities differs as well.
Again, not using RG as a metric but some universities, especially those with a lot of international students from a 'normal' background (not super rich mummy buys a flat) have a very self-motivated atmosphere. Students organising events in partnership with employers, for example. Rather than just 'attending' them. Making their mark.
By contrast, others are more chilled. And think that the above is hothousing.
I don't think either is bad, but it depends on what you are like. For me, coming from a not 'MC' background (international scholarship student) I really benefitted from all the pushiness. I didn't know that you could just approach people, didn't know how to forge my own path. Didn't know the importance of doing stuff for my CV if the people around me hadn't talked about it all the time!
If I had gone to a more chill university I would probably have been kicked out of the country as the visa was very strict and I needed a job before graduating.
I do a lot of outreach work and I find that those from less 'well-regarded' universities tend to have a lot of this problem. They have 'some' PT jobs and maybe a uni sport/club. But they think that it's enough to stand out. The ones I interview from 'less well regarded' unis with 'generic' degrees always tend to be from a more MC background from the way they speak , and the activities they have done.
Again, note my careful use of the word 'well-regarded' as opposed to 'RG'!
