1. All companies have a history and it is a benefit to know a little about it. Knowing the organizations beginning ground work will help you to see how the company came about. It gives you an idea of how far the company has come from it's initial setup. Usually an interviewer will ask you some sort of question pertaining to this. You want to come off as well researched.
2. When walking into a room whether it is with one person or ten you need to shake everyone's hand and look each person in the eye when introducing yourself. If you have a hard time with names it is always a good idea to say that person's name back to them. Here is an example; "Hi, Dick Thompson". "Nice to meet you Dick", this usually helps you put a face with a name. Next time you run into Dick or speak with him on the phone, you will be able to remember his name. This will help impress the interviewer.
3. Nothing looks worse to the employer than being unprepared. If you are not prepared for the interview than who knows what is in store for the future? You always want to bring in extra copies of everything that you have given the employer before. Even if the employer doesn't ask for one it is good to have one on you. Sometimes, if in a rush the interviewer will have misplaced their copy and this way you can impress them. They will not have to run back to their office or rummage through the drawers. You have a copy ready to hand them because you came prepared.
4.  Keeping composed is difficult. Before an interview if your nerves are getting to you take control of the issue. Depending on your situation exercise can help. Sometimes it can take away some of the anxiety one might feel. Focus on your breathing before the process begins. In a lot of cases before an interview you spend some time in a waiting area. Be prepared for this and take something with you to distract you from the pressure you may feel. Looking over the job description or nervously trying to memorize your résume is not going to help with anxiety. Bring a magazine, crossword puzzle, or something inconspicuous. This will keep your mind focused on something other than the process. All of these steps will help impress the interviewer.
