There are two interviews, both are semo-open so they have only seen your personal statement. The first interview is group, 3 applicants, 3 interviewers. The second interview is one on one. All the questions I received were related to my personal statement, or to something I said during the interview. I got no ethical or health care questions, though apparently some people did. Overall, it was very relaxing and not intimidating at all. Everyone makes you feel very welcome.
