Over a 50-year management career in the military, government and private business, I've interviewed hundreds of job applicants. Of course, early in my working years, I was on the other side of the desk, applying for a job. So, I know both apects of the interview process. The most important part of it is preparation. First, you must have the qualifications and written proof of them before applying for most jobs that require higher education. Even after my careful screening of query letters before inviting applicants for an interview, many came to me with fake resums, I made sure I gave a simple ten-minute test to all as they arrived. Surprisingly, at least a quarter of the applicants either failed the test or were so embarrassed they just walked out. Preparation, in addition to being a fully-qualified applicant, means sprucing up both your appearance and your speaking ability. Unless you're applying for a job with a rock band or circus freak show, dress in conservative business attire. No green hair, nose rings, visible tattoos or other add-ons that could turn the interviewer off. Sorry about personal freedom of expression and all that, but you're visiting someone else's turf and you must comply with the rules. In your speaking and general attitude, you must be upbeat, positive and grammatically correct. How many college grads who applied for jobs with me couldn't get through a sentence without using the word "like" a dozen times. Total turn-off. Also, some came with a dejected, unhappy attitude of, "You wouldn't hire me." They never said the words, but they were always right about the outcome. No matter how many rejections you've had before your new interview, do not let them influence your attitude during the new one. Another need, and too many applicants forget or ignore it, is to do heavy homework on the potential job. Then, during the interview you'll have a chance to express your knowledge of the company/agency, its history, how he/she can fit in and other important facts. I was always pleasantly surprised when an interviewee added pertinent information to his/her pitch. So, in heading out for that new job interview, first look in the mirror and smile. You're well prepared to give it your very best shot. Good luck!
