read amcas looked on sdn feedback (ethical questions)
What impressed you positively?
Hospital is beautiful. School is connected to undergrad campus. The third year is a research year which can be used for just about anything you can convince people to sponsor you for.
What impressed you negatively?
Students seemed a little worn out. Durham is the middle of nowhere...I don't think that there's much to do there besides study or do something at the university.
What did you wish you had known ahead of time?
How isolated and rural the Durham area is.
What are your general comments?
The interviewers definitely asked questions meant to challenge your thinking. There is one interview for more "personal" side of your application and another for the "ethical/thinking questions" side. Some people may find it stressful but I thought that the interviewers were very nice.
