Disable any phone features that may interrupt the conversation. Make the call from a private, secluded location. Have water nearby to assist with dry mouth, any necessary notes and multiple writing utensils at your disposal.
Upon receiving the telephone call, answer the telephone by name. Print out a physical copy of the job description and any relevant personal information such as a resume. Research the interviewer prior to the phone call to gather a mental image of the caller. Consume honey before the interview, as honey soothes the throat. Talk or sing before the interview to stretch your vocal chords. Dress professionally to enter the proper frame of mind for the interview, even though the call is audio-only.
