2. Never come unprepared for the interview: The interviewer is sure to ask you questions related to the company. So before appearing for the job interview you must do your home work well, as you should research about the company through the company website well in advance. If you decline to do so, you won’t be able to answer the company related questions for which the interviewer might think that you are too lazy, and that you have not taken little pains to research about the company you are interviewing.
