"We're considering two other candidates for this position. Why should we hire you rather than someone else?"

Do not be distracted by the mention of two other candidates, you don't know anything about them and they could be fictitious. Focus on what strengths you bring to the table. These should be consistent with the four things most employers are looking for in candidates during the job interview: competence, professionalism, enthusiasm, and likability. Remember, they are looking for chemistry between you and them. Be prepared to summarize in 60 seconds why you are the best candidate for the job. Also, let the employer know you want the job and you will enjoy working with them. A lack of interest in the job may indicate a lack of enthusiasm for the job and them.
