ubulu,
more suggestions for your interviews. since you only got the 1 interview so far you need to tailor yourself to the program as much as possible. for example, if the program is a clinical program and you are interested in basic research, don't keep talking about the basic research you want to do, talk about how you truly want an amazing clinical experience....at the same time don't say the opposite of your CV and application, just lean towards what they are looking for. good luck
