I'll throw in my two cents here too.
1) Dude I was really impressed by the EMT training. Ahaha. I suppose if you already have a certification it's not a big deal, but I thought it was pretty cool that you serve as an EMT for a bit. I don't know if that's their major selling point though.. it's more of a perk.
2) I wouldn't say they grill you on the curriculum, but they do ask "Why Hofstra?" or "How did you hear about us?" No need to memorize course names or anything haha. I think it's good to understand what Hofstra is trying to do with their curriculum in a general sense. Like Ryan1514 said, they pretty much go through that in the morning and even show you a video of how they do their PBL. I think that will tell you a lot about their curriculum and the kind of students they think will succeed at Hofstra. Almost every student I spoke with stated the curriculum as their number one reason for attending Hofstra.
3) I didn't really get the job interview atmosphere Ryan1514 did. My interviewers knew my file... all the way down to what my LORs said without having to look it up. It's very possible that they tailor their questions to each person so you may not get the generic job interview type questions. But I agree, they're not there to stress you out, just to get to know you better and see if you have the personality to do well at Hofstra (and this is something you do or don't, I'm not sure you could fake it anyways so try not to stress about it and "prepare" for it). I got a lot of questions about my undergrad, questions about why and how I decided on medicine, and only like one teamwork question. To be fair, I think my personality and teamwork traits were evident from the rest of the interview so maybe they didn't feel the need to ask me to provide specific scenarios. Both interviewers went a little "off-script" I think, and actually gave me hypotheticals based on what I told them (I got the sense these weren't traditional interview questions and they were just honestly curious as to what I thought about certain things). They were really interested in my thought process and what I would do or say given certain scenarios. For example, I mentioned something about peer review at my work--and then my interviewer asked me what I thought about anonymous vs non-anonymous peer review in residency and which I would prefer. With my other interviewer, I was telling him about how these parents were really upset with a doctor I was shadowing, and I was a bit torn about it because I understood why the parents were upset even though I felt that the doctor did everything he could. The interviewer then asked me what I would have said to the parents if I was the doctor.. and it really made me pause and think. Even though I stumbled in my answers, rambled a bit, and let the conversation fall into silence while I thought about their questions (read: everything that usually makes people feel like they had a bad interview), I thought Hofstra was my most genuine interview because they made me really think and reflect on myself. In a lot of ways, even if I had reservations about the curriculum, I have confidence in the interviewers and the admissions committee to select only the people they think would succeed here.
I don't know if that was just a long blog post or if that will actually help you. Really, try not to stress and be too nervous. Be yourself, know yourself well, and trust that if you have the personality to do well in Hofstra, they will see that and you don't have to actively "sell" yourself as everybody says you do in an interview. Hope this helps!
