There are few times when this technique is warranted. Answer the Candidate's Questions. At the end of the evaluation phase the interviewer should indicate that it is the candidate's turn to ask questions. The interviewer can use the questions as a way of describing what makes the employer firm unique and stressing areas of excellence. The interviewer should avoid discussing negative aspects of other firms.
Negative comments are unprofessional and probably counterproductive.
Explain Follow-up Procedures. In the last phase the interviewer should try to give the candidate some idea of the decision process and an estimate of the timing. The decision process should include some consideration of references. Whenever I think of references I think of the story about two passengers on an airplane who started discussing their jobs. One was a CPA firm recruiter who explained how he interviewed students on campus and then invited the better students into his office for a follow-up session after which an employment decision was made.
