Some people like to interview for jobs. Most people would prefer a root canal. Performed by a yak. As in so many other endeavors, proper preparation for a job interview can help the candidate present him or herself in a more professional, effective manner. This does not mean memorizing canned responses and producing them on demand.
Parrots do that.
People develop a response which reflects their own experience and philosophy in a concise and positive way. Remember that everyone who is interviewing is not necessarily a good interviewer. Learn to recognize a poor interviewer and help them discover all your good points. Research, research, research. Absorb annual reports, press releases, and other company-issued material to see how the company perceives themselves.
