When you begin your phone interview, try to get the name and title of the interviewer and write it down. That way, you can refer to it throughout the interview (people likes to hear their names -- that's what Dale Carnegie, the dean of influencing others advises). You may also be able to write a post-interview thank you note or email if you've also managed to get contact info.
You should "tickle interviewers' interest" by answering most of their questions, but give them a reason to meet you in person for the tough questions, advises Brenda Fabian, director of career services at Susquehanna University in Selinsgrove, Pa. "Tell the interviewer that you can better answer that question in person, and ask to set up a meeting to better explain your qualifications. Decide beforehand which questions can best be put off. You can use this tactic two or three times in the same conversation, if you are comfortable with it."
Remember, says Cynthia Favre, director of career management at Gustavus Adolphus College in St. Peter, Minnesota, a key goal of the phone interview is to advance to an in-person interview. "As the call winds to a close, tell the interviewer you think you can better discuss your qualifications in person and suggest a day and time you can be at their office."
