A job interview can be the most intimidating part of the job search process. Making a good first impression is a very important part of the interview. Most people make a judgment about a person within the first few minutes. If you are prepared for your interview you can make sure that your first impression is a good one.

Preparing for the Interview

Do your research. Learn about the company history, its employees and the specific job that you want. Review the job ad for the description, qualifications and requirements of the position.

Clarify your objectives. Before you can say that you want the job you need to be clear on your own interests and career goals. During the interview you should be prepared to explain why you want the job and why you thing that you would be a good fit.

Read interviewing tips books on to find common interview questions. Plan out your answers to some standard questions.

Get a good night's sleep the night before the interview. Be sure to eat a good meal before you head to the interview.

Dress professionally. You will want to dress appropriately for the industry. You should blend in but also be sure the outfit is your style so that you will feel comfortable.

Bring supplies. Have a pen, paper and multiple copies of your resume with you.

During the Interview

Arrive early. If you are unfamiliar with the location of the company you should figure out the route before heading to the interview. You may want to drive the route the day before to make sure you know exactly where you are going.

Arrive ready. Your interview starts as soon as you arrive at the company. You never know who you will meet during the time that you are at the company. Just because you aren't in an actual interview with someone doesn't mean that their impression of you might affect the hiring decision.

Actively participate in the conversation. Listen actively, make eye contact and shake hands.

Come prepared to discuss and, if necessary, defend your resume and any weaknesses in your job history.

Ask questions. Have questions prepared in advance. Ask questions about the job duties, expectations and management or communication styles.

Be yourself. Answer questions honestly, but remain positive. If you are asked about an unpleasant previous job or your weakest characteristic, answer honestly but leave your interviewer with a positive impression. Let your personality shine through and don't let your nervousness block your true self.

Thank everyone immediately. Thank your interviewers individually before leaving the interview.

After the Interview

Write thank you notes. As soon as you can, you should write a thank you note to each person who interviewed you.

Recap any major assets that you would like to remind them of and correct any issues that you feel might have been misunderstood. Keep the letter short and tell them why you are still interested in the job.

Explain why you are still interested in the job in a clear, convincing manner.

Keep the letter brief and positive.
