This is a critical part of your preparation.  There are interviewers who will ask you, “What do you know about our company?”  You do not want to be left red faced because you have just ‘simply pitched for your interview.’  Always research the company you are going to.  Obtain a website address and ensure that you are familiar with their products and services, when they were established, how many branches they have and any special awards they may have received.  To the prospective employer this shows your initiative and interest.
