My interview was in September because it took place overseas. Generally all students applying for the same course will have the same one interviewer, regardless of college. Overseas interviews are shorter because there are many applicants and a limited timeframe. This can work either for or against you: interviews tend to be less rigorous, but you have less time to impress. My interview took around 20 minutes, and was centred on maths and very very basic economics.

We started off with some graph sketching followed by a problem about externalities (no prior knowledge required). The graph sketching was pretty unique and difficult - I recall some really funky functions. But don't worry, just try your best and be systematic in your graph transformations. I failed to give a complete answer to one of the externality questions, but my interviewer was very encouraging.

Throughout the interview, he would prompt me instead of feeding me the answer - bear in mind that they're looking for teachability. Just stay calm, be open to their suggestions and think out loud! We didn't discuss my personal statement or either of the 2 essays I submitted at all - it was purely academic.

In preparing for the ECAA, past papers and the Oxford TSA are your best friends! Familiarise yourself with the format of the paper and time yourself well during the actual test. If you're looking for books to discuss in your personal statement, try hitting up the Cambridge, Oxford, LSE, UCL etc reading lists for some inspiration/more rigour.

Try to walk out of the interview room having learnt something new. And don't beat yourself up or continually replay the interview once you're finished - your best is enough! Put the interview behind you & focus on whatever you can do next (admissions assessment/2nd interview/school exams - or meeting your offer!).
