How to properly answer the question,  “why you’re the right person for the job?”

Each position you interview for has specific goals and expectations.  Based on the company, you should try to go in understanding the position. This can be done by researching the company, looking up other job descriptions for the same position and, if possible, talk to other people who work for the company.  If you are still unclear, include it in the questions you ask in the interview, determine how your skills and experience support those goals, explain why these are in line with your own values and goals, and then be prepared to incorporate it into why you are the right person for the job.

Be enthusiastic (but don’t overdo it to where they are questioning your enthusiasm) about the opportunity to work for the company and within their team and make sure the interviewer is clear about the fact that you really want this job.
