If you call a school requesting information about a position, make sure you have done some preliminary work. Asking questions that suggest you know nothing about the school or even its geographical location makes a listener wonder how serious you are about the job. Present yourself clearly, unambiguously, and in a reasonable amount of ink. You will be one of 50-250 applicants. During the initial stage of a search, a committee member may spend ten minutes or less reviewing your letter and vita.
Faculty are busy people.
As fascinating as you may be, they do not have an unlimited amount of time to review a thirty-page document, especially with one hundred applications still to be read before the committee meeting in two days. Send an application that will interest a committee. Veterans of search committees can sniff out a hastily written, generic application easily. Do not waste their time or yours by sending something half-baked. Individuals highly trained in critical analysis and interpretation will be reading your letter.
