It is said that, 'first impression is last impression'; One has to be careful while going for interview. You have to be confident while answering interviewer, present yourself correctly and GET THE JOB !!! As simple as that…..

During interview, you need to focus on,

Grooming

Wear a professional business suit. This point cannot be emphasized enough. First impressions are extremely important in the interview process. Women should avoid wearing too much jewelry or make up. Men should avoid flashy suits or wearing too much cologne. It is also important that you feel comfortable. While a suit is the standard interview attire in a business environment, if you think it is an informal environment, call before and ask. Regardless, you can never be overdressed if you are wearing a tailored suit.

Research about Organization

It is to your advantage to carefully research the job and the organization. There are many ways to do this. You can request printed materials from the employer, such as annual reports and job descriptions. This is an entirely appropriate request, so don't hesitate to make it. Use your library and career center resources. Ask colleagues, friends, and faculty about the organization, and about any personal contacts at the organization they might have. Look at the organization's home page. Knowing about the job will help you prepare a list of your qualifications so that you can show, point by point, why you are the best candidate.

Punctual and professional

Always arrive early. If you don't know where the organization is located, call for exact directions in advance. Leave some extra time for any traffic, parking, or unpredictable events. If you are running late, call right away and let someone know. The best time to arrive is approximately 5 - 10 minutes early. Give yourself the time to read your résumé one more time, to catch your breath, and to be ready for the interview. Once you're at the office, treat everyone you encounter with respect. Be pleasant to everyone as soon as you walk in the door.

Organize your Original Papers

Carry a portfolio notepad or at the very least a manila file folder labeled with the employer's name. Bring extra résumés and have the names, addresses and phone numbers of references, in case the employer asks. Also, bring a list of questions for the employer. You may refer to your list of questions to be sure you've gathered the information you need to make a decision. Do not be preoccupied with taking notes during the interview.

Understand Yourself

You will make the interview process easier for the employer if you volunteer relevant information about yourself. Think about how you want to present your strengths, experiences, education, work style, skills, and goals. Be prepared to supplement all your answers with examples that support the statements you make. It is also a good idea to review your résumé with a critical eye and identify areas that an employer might see as limitations or want further information. Think about how you can answer difficult questions accurately and positively, while keeping each answer brief.

Positive Attitude

Never say anything negative about past experiences, employers, or courses and professors. Always think of something positive about an experience and talk about that. You should also be enthusiastic. If you are genuinely interested in the job, let the interviewer know that.

Show your interest

One of the best ways to show you are interested in a job is to demonstrate that you have researched the organization prior to the interview. You can also show interest by asking questions about the job, the organization, and its services and products. The best way to impress an employer is to ask questions that build upon your interview discussion. This shows you are interested and paying close attention to the interviewer. It is a good idea to prepare a few questions in advance, but an insightful comment based on your conversation can make an even stronger statement. At the end of an interview, it is appropriate for you to ask when you may expect to hear from the employer.

Save discussion of salary for later

Find out as much as you can before the interview about the salary levels for the position you are seeking. Do not bring up the issue of salary during the first interview. If the interviewer asks about your salary expectations, give only a general answer, such as that your expectations seem to be within, or close to their range.

Follow up

You should write a thank you note within 48 hours after an interview, even if the interview (or the interviewer) was not productive and/or you are not interested in the position. It is important to say thank you for the time the interviewer spent with you. This letter should be brief. (Refer to the section on writing thank you letters.)

Practice for Interview at Home

Prepare a succinct, clear answer to each of the questions in the interview questions section. Practice answering questions with a friend, or in front of a mirror. Ask your friend to give you constructive criticism on your speaking style, mannerisms, and poise. As you practice, avoid colloquialisms, such as "like" and "you know." Make sure you don't script all your answers-you'll sound as though you're reading cue cards! It's important to prepare yourself for talking with complete strangers.
