<p>Hi</p>
<p>I applied tp Oxford for E&M this year (starting Sep 2006) and already had my interview back in Dec. It is extremely different from interviews at american colleges. There’s nearly nothing about extra-curriculas or past achievements (like APs, grades in general etc.).
They (up to three interviewers) basically ask you shortly why you want to study E&M and why you think you would be doing great and the proceed with some tasks mainly based on logical and analytical thinking. They do not require too much background knowledge on E&M but you are likely to be asked some things if they know you already did some economics.</p>
<p>If you want to know anything in particular feel free to pm me.</p>
