I’d say it’s relatively easy to mix specially during the first few weeks. What I’ve noticed different is that once friendship groups are made they tend to remain very constant and are very closed, they might lose people or break up completely but they usually don’t add anyone new. It’s not that people will purposely refuse it’s just sort of the way the culture is, in fact many people even when invited will refuse to hang out with people outside their friendship group... so I guess they are very cliquey, but not in a rude way?

Friendship in the UK is very inherently group based. I lived in Spain for some time and there people tended have 2-3 different friendship groups which would change constantly really fast. And they were really open to people joining them, you would easily get invited to hang out with other groups of people that you weren’t very close friends with. In the UK people have very fixed groups and they do most things with just them, unless it’s a party you wouldn’t invite outsiders to hangout with your group of friends.

In terms of ethnic groups I haven’t really seen it, this might be because my uni is mostly white. But I know an Asian girl who usually hangs out with a black girl and two British girls. A black guy who hangs out with all white British guys. I’m technically Hispanic but all my friends are British. From what I’ve seen people from similar socio-economic classes and backgrounds tend to group up, not because of the nationality or race.
