Hello there!
I don't have any resources to share but I have some tips:
-Re-read your personal statement and know what you talked about it.
-Just because you sent off your application doesn't mean you should stop doing wider reading and keeping up with medical news - in fact now more than ever you should keep up with medical news and keep exploring Medicine!
-Give some thought on what you'd answer on questions that are very likely to come - why do you want to be a doctor, why that particular uni...
-If you can, there are lots of videos online on interview tips and preparation and some mock interviews as well.
-Get your family, friends, or someone from your school's Medicine society to help you do a couple of mock interviews. But don't overdo them. You don't want to sound rehearsed!
-You might be stumped by some questions, and that's fine! Just think out loud, Medicine largely involves being stumped by problems and then being able to apply some logic and thought to them.
-Easier said than done but... relax!
Hope this is helpful, and I wish you the best of luck
