Posh accent at interview?

You'll just end up looking like a tool. Making sure you pronounce your words correctly and saying things like "My friend and I" instead of "Me and my friend" would probably help your cause though.

Nah, people who say things like this to try to appear smart always end up getting it wrong and saying things like, "It interested my friend and I," and it's just lulzy.

It isn't really smart, its basic English... or is even that frowned upon these days? I meant when saying something like "My friend and I went to the cinema." If you use "Me" instead, it would be saying "My friend and me", which, if you think about it is like saying "Me went to the cinema" once you remove the friend from the equation. Don't want to come off as a dick here - I got B/C in English at GCSE btw - just saying that its something pretty basic that a lot of people forget and it IS noticed, trust me.

...that was my point, I just used the opposite example.

It interested my friend and I is incorrect.

My point was that it doesn't apply IN EVERY CASE to say "My friend and I." In some cases it is incorrect.

Ah right, sorry, I thought you were meaning that using it in general was considered trying to be smart. Its late, haha!

OP, all the other posters here are just trying to prevent you from getting into oxbridge. For the interview, speak like you are part of the British nobility. Wear full white tie, a top hat, silk gloves and a monocle, and carry a cane. Have yourself chaffeured in a Rolls Royce to the university and have your valet shine your shoes just prior to entering the interview room.

I jest.
