Which Oxford masters programme is easier to get in?

[Philosophus1.618]

I thought this was the best place to ask these questions, so...

Which Oxford masters programme is easier to get in; Economics, Sociology or Philosophy? I have a client who wants to know.

Also, does it matter which undergrad uni he went to? He currently studies at a top uni in Scotland (St Andrews or Edinburgh - I am not at liberty to say which, sorry). Currently studies Economics and Philosophy, but could switch to Sociology as he like it as well.

Also by studying which is it easier to gain a job at a university?

Thank you all for your answers!
