With the increase in call centres and other-telephone based businesses, more and more companies are using telephone interviews to check the telephone manner and skills of potential staff.

Telephone interviewing is not usually a substitute for a good old face-to-face interview, however. They're a quick and easy way to identify and discount unsuitable applicants. In-depth interviews for senior and managerial positions are ideal when short-listing candidates for a face-to-face interview. This paper gives 10 tips to help you be at your best when interviewed over the phone.
