To be honest, I have always disliked attending a job interview. I understand that they are a necessary evil, but I have always dreaded them. I think that it is all about showing that you are good or bad at job interviews, and not whether you are good at the job you're applying for. Some job interviewers approach the interview very scientifically. They read up on techniques and psychological profiling to help them in their task. You must know how to answer job interview questions if you are about to attend a job interview.
You have to master the art of telling people what you think they want to hear if you want to succeed at job interviews. You also have to exhibit a degree of honesty while you answer job interview questions. This is because we all exaggerate our experience and skills a bit from time to time.
