Practicing for a telephone interview will give you confidence that you wont blow the real thing. ask one of your parents' or a friend to conduct a mock interview with you. have him or her phone you and ask an interviewers questions. its also to get a spouses' or father's-in-laws critique of your answers. ask one of them to listen in, or, whats even more useful, tape record the mock interview for later analysis. pay attention not only to the content of your answers, but also to the voice quality; is your's clear, without too many "uhm's" "you knows," and "likes"
