<p>Generally otherwise-qualified candidates are making several very severe mistakes. Catastrophic interviews, from what I’ve seen, are pretty rare.</p>
<p>Much more frequently, these kids don’t know how to pick schools to apply to, and they apply very late in the process, or they don’t have any research and are applying to research-heavy schools. Mistakes from mdapplicants are actually usually pretty obvious, right there on the webpage.</p>
<p>A few common mistakes.</p>
<p>1.) It is always a mistake to apply to fewer than ten schools.
2.) A significant portion of the pool (I would say two-thirds) must be schools where you are significantly above their means.
3.) If a school cares about research, you should have done research. Otherwise don’t bother.
4.) You should apply to every single school in your state, public or private, as well as any schools in the state where you did undergrad.
5.) If your primary is sent off after September, you’d better be **supremely **qualified for every single school you apply to – perhaps four MCAT points above their mean.</p>
<hr>
<p>How schools handle interviews varies. Some schools explicitly say that all that matters is the interview – that your previous application really doesn’t matter anymore. In other words, once a 36 and a 40 both get interviews, the four-point difference on the MCAT doesn’t matter. Even slight differences in the interview trump significant changes in, say, GPA.</p>
<p>Some schools take the opposite approach. As long as your interview is not a complete disaster, it doesn’t matter. So long as you don’t manifest any obvious sociopathic tendencies, small changes in MCAT and GPA are still very important. A mediocre interview is just as good as a spectacular one.</p>
<p>Most schools are in between. A 40 is still at an advantage of a 36, and a great interview is better than a good one.</p>

<p>BRM’s excellent answer is very thorough. Here’s the Cliff’s Notes:</p>
<p>Applications move in three stages
a.) Primary (MCAT, GPA, Essay.)
b.) Secondary (Essays.)
c.) Interview</p>
<p>You can be rejected between steps A and B (“presecondary”), or between steps B and C (“Postsecondary.”) You can also be rejected after Step C.</p>
