There are likely many qualified candidates for the position, and the interviewer wants to see why you believe you are the best candidate. They want to hear what makes you the perfect person to hire for their organization. Review the job description and use words that are in the qualifications for their ideal candidate. For example, if the job description says they are looking for an energetic, creative, and compassionate Therapeutic Recreation Specialist with at least three years of experience and specific qualifications, use those keywords to emphasize why you are the best candidate for their organization.
