Description: Just as you must know yourself before you begin an interview, so too must you know your prospective employer. Knowledge of the company helps you tailor your responses to questions and gives you confidence. It shows the interviewer that you care about the company and want to make a well-informed decision, and it gives you fodder for posing impressive questions to the interviewer. All of the information you gather will help you anticipate the company culture and gauge the expectations that they will have of you.
