Here are some things that will lead to an auto-reject at my school:
Having multiple misdemeanors or any sort of felony, especially involving theft, drugs, or violence.
Showing a lack of ownership for IAs or misdemeanors ("it was the cop's fault I got busted the second time")
History of cheating or being expelled for honor violations.
Having a red flag LOR (I see about one of these a semester)
Being clueless or a very poor listener at interviews. I have little patience for someone who starts to answer and then asks "could you repeat the question?"
Being a babbling idiot at interviews
We have a group interview, so looking bored or not paying attention to what's going on.
Being arrogant
Being scary (this HAS happened!)
Matriculating at any other medical school and flunking out, or leaving for a poor reason.
Lying during interviews (this has also happened)
Being a hyper-achiever who wants to answer other people’s questions, instead of waiting one's turn.
Being a robot or unable to display any sort of emotion, or having a flat affect.
Being immature.
Now, I'm sure someone is going to chime in that "yeah, but interviews are stressful". No doubt they are, but so is tying off a spurting artery on a MVA victim, or dealing with an acting-out psychotic patient. Thus, with all the people we interview for our limited number of seats, the seats go to those who display grace under pressure. Panic is not an option for a doctor; clear-headed thinking is.
I just wanted to start a thread where everyone can weigh in on examples of what they have heard that lead to auto rejection or, in the case of adcoms, examples of what they auto reject someone for (or, at the very least, severely penalize you).
I'll start:
-Being rude to a secretary
-Being asked about a low grade and blaming it on the professor
-Saying you are going into medicine for the salary and/or job security
