Conduct the interview in a private location where you will not be interrupted or distracted
It is preferable to conduct the interview over a land line rather than a cell phone to ensure the best connection.
Sit up straight, in a chair, at a desk or table. Do not lounge on the couch or in a bed. Do not conduct the interview “to go” while you are on the move.
Have a copy of your resume, cover letter, application, and job description accessible
Prepare some notes highlighting your top skills and strengths. Your notes should be in outline form not an essay. Keep them organized so you can refer to these during the interview. However, avoid shuffling the papers or sounding like you are reading from your notes.
Smile as you would in a face-to-face interview. A smile can be sensed over the phone and communicates enthusiasm and friendliness.
Speak slowly and annunciate clearly.
If there are multiple interviewers on the call, write down names as introductions are made and take notes so that you can address individuals by name.
Since you will not have non-verbal cues, verbally clarify information or points of possible confusion. Ask, “Have I given enough information?” “Do you need more detail?” or “Did I answer your question satisfactorily?”
If you do not think that you heard a question correctly or clearly, politely ask the interviewer to repeat the question.
Write down a list of questions for the interviewer.
Ask for the spelling of the interviewer's name, title, and email address so that you can send a thank-you note.
