I've heard talk about "magic numbers" for # of interviews for matching into plastic surgery, but have heard varying things about the definition and what the number is. Is there any hard data or accessible sources that the magic number comes from or is it just hear-say/made up?
Disclaimer: this is one of the "newer" papers I know of, but it was published in 2011 and based on 99'- 09' match data, and as we know things have changed since 09'
The Magic Number and the data you speak of taken from "The independant plastic surgery match" (Harper et al, Ann Plast Surg 2011; 66: 568-571) :
The statistic that most candidates would like to know is the relationship between the number of programs interviewed and the rate of a successful match. Along the interview trail, many candi- dates discuss this “magic number,” yet none has statistical data to support their claim. Table 8 shows the match rate as it pertains to the number of interviews attended. It also shows the average number on their rank list to which the applicant matched. Although an individ- ual may successfully match after interviewing at only 1 program, and vice versa an individual who interviews at countless programs may not match, a noticeable trend is demonstrated. After 5 inter- views are attended, a steady incline in a successful match rate is noted. Ultimately, all 26 of the applicants who interviewed at 13 or more programs successfully matched.
Table 8 shows details but briefly the # of interviews and correlating match %age
1-41% (I assume that people only interviewing at 1-3 places includes lower candidates obviously but likely this number is skewed a bit b/c probably also includes competitive applicants that were geographically constrained due to family/kids etc)
5-50%
10-80%
>13-100%
