I doubt it.
I mean, this might be expected if you were interviewing for a job at a law firm or a large well organized company with some HR. You have to remember that you will be interviewed by doctors and students.... maybe a dean. Hate to say it, but most doctors are pretty busy, and probably don't spend a lot of time learning the subtleties of making someone feel like an interview is going well. Look, you will feel like your interview "goes well" if 2 things happen: 1. You don't choke on a question or back yourself into a corner. 2. The interviewer is "nice." By "nice" I mean he asks conversational, non-confrontational (i.e. prove yourself) type questions.
Now, in my experience, which is only a few med school interviews, but tons of non-med school interviews, its more about whether you connect with the interviewer and they feel you are genuine. You know how you can tell when someone is full of sh**? Well, an interviewer can also tell if you are full of sh**. At my most recent interview, my interviewer said he like my answers, and that he HAS talked to people who he thought were exagerating, or were non-genuine. So be real... Thats the best you can do.
Having been an interviewer myself, it is not just the first 30 seconds that count. Sure, first impressions are important, but never under estmiate the negative effects of stuffing your foot in your mouth 20 minutes into the interview.
