With confidence and a smile. Be honest and sincere first and foremost. Now think - Why would YOU hire you?

Here is an example: "You should hire me because I will be an asset to your company. I'm hardworking, honest, a team player and great with customers. As you can see by my resume/application I've got the experience you are looking for in this position. Most of all, I'm reliable and will always be here when expected."

Then, make a positive statement such as: "I look forward to being a part of your team."
A lot of people have a problem in answering this kind of question, too afraid to sound conceited. But this is the part of the interview to sound conceited!

- Highlight any parts of the job or job description that sound like you. TELL the intervewer how closely you match the job description ("I'm an excellent writer." or "My great personality and helpfulness are perfect for customer service." or "I know many of the required software programs and I'm also a quick learner!"

- Tell him or her what a hard worker you are, that you've hardly missed any work in the past, that you are talented at whatever the job is, etc. However, do NOT lie about any of this stuff! Only say it if its true!

In formulating your answer, be sure to address these areas:

1. Determine their goals for the position. This should come up during your research into the company and into the position. If possible, talk to others who work for the company. If you are unclear on this point, include it in the questions you ask at the interview itself and be prepared to incorporate it into your answer.
2. Show you have the skills needed for the job. Based on the goals you have identified in step one, determine how your skills and experience support those goals. If necessary, refer back to your "60-second commercial" for a list of skills you possess.
3. Articulate shared values. Again, this should come up in your research. Look at the company’s mission statement and regular business practices. Explain why these are in line with your own values and goals.
4. State your interest in the position. Be enthusiastic about the opportunity to work for this company and/or within a certain team. Be sure that the interviewer is clear about the fact that you want this job.

The most important aspect of this exercise is to make you comfortable in identifying and articulating the skills you possess. Even with a prepared answer, it is important to be flexible within the script itself. You may need to modify the specifics based on the situation.

If an important issue comes up during the interview, be prepared to adapt your answer accordingly. For instance, if the interviewer stresses the need for a certain skill, you will want to address that, even if it was not one of the skills that you included in your original script.
