I’m not an interviewer, so not really. For me (and I think this is common, but I’m not sure), it is not so much what they say specifically, but that they have examples to back it up. If someone tells me they want to serve but have very little non-clinical volunteering or zero experience with the military population, I might question it. Either they really aren’t in it for service or they think they are but don’t actually have the experience to know.
On the other hand, someone who has been volunteering in the community or is prior service or did peace corps or whatever, they have some evidence to back it up.
Doesn’t mean you have to be Nobel peace prize material by any means lol.
But again, I’m not an interviewer. This is just my own opinion and a little based on what Col Saguil and CAPT Liotta have said to me.
As far as what questions to ask, it’s hard to say but generally try not to ask stuff you can look up easily. Also keep in mind that a lot of the interviewers are going to be volunteers who may work at Walter Reed and might not know a ton about the curriculum or specific things at the school. I think I asked a question to my first interviewer and he didn’t know, so I said okay cool and that was that lol.
