Clearly the variations in applicants' competitiveness on paper plays a role here, as does an applicants ability to win over a residency committee with his or hers affability on interview day. But these things aside(and assuming one has been lucky enough to get many interview offers), what is a reasonable number of interviews to attend? One can spend a small fortune trying to go to every interview that he or she can. Also, if someone decides to go on 23 interviews but matched at their #2, I wonder if letting go of a few of those extra interviews may have helped someone else less fortunate.
I know that there isn't an exact answer to this question, but I have heard 10 interviews mentioned as a good number. Is this true? Are there many examples of people who ended up matching at a place that was lower than number 10 on their rank list? Any incite is appreciated.
