You'll find this question near the end of the interview. If you feel you have something special to offer that didn't get mentioned or prompted in the interview, then say it here. Avoid using cliched buzzwords like "hard-working," "fast learner" or "gets along well with others." Phrase your response in terms of what you can do for the employer, not how the job can benefit you. Use this question as your opportunity really to sell yourself to the hiring manager.
