Instead of just someone with skills and education, you want to be seen as a whole person. There will be many people who are qualified for a job, but only one will get hired. The personal touch can convince an employer that you are the right applicant for the job. Your second goal in an interview is to be sure the job you are applying for is the right one for you. You should ask questions of the employer concerning the company, its products, the hours of the job, work expectations and benefits.
Many people dread the interview.
They may get sweaty palms and knots in their stomachs before the interview. Nervousness is unavoidable, given the importance of an interview to your chances of getting a job. However, a large part of the fear of an interview comes from lack of experience. Being prepared has several advantages. Preparation gives you confidence in your ability to cover most of the important information the employer wants to know.
