All I can say is be relaxed and BE YOU! Have your answers for the standards: Why and when did you decide to be a doc? why here? Why should we pick you? Additionally, know your strengths. And finally, be prepared to explain/account for your weaknesses, if you have any (ha ha). From my experience, they try to capitalize on this and see how you maintain composure when the subject comes up.
As far as relevant Irish medical news? Do some research...quickly! Nice school. Sounds like a great opportunity. Good luck.
