PAUSE
For the interviewer a pause is a passive yet excellent tool for eliciting more information. After a subject answers a question or finishes the recitation of his version of a sequence of events, try waiting a few seconds before you respond. With your facial expression and physical demeanor give the subject the subtle cue that you expect that there is actually more information that he or she should divulge. Your pause can also give the subject the impression that you may know more than they realize and you expect them to be forthcoming.
