Question special

This is the second part of a three-part question, which Dr. Rosman answered a bit with the very valid reminder that there's a lot of variety in 30,000 people! In medical school rotations, few individual faculty members can have a disproportionately large impact on student perceptions of each specialty. How reliably do clerkships expose medical students to a specialty's "personality"? What do you recommend to a student whose personality clashes with faculty in a preferred specialty, especially where letters of recommendation are concerned? How significant a consideration should perceived "fit" be for students in choosing a medical specialty with respect to occupational satisfaction? What about for MD/PhD students who want to continue doing research in the field?
