These can often be found on the Internet, and knowing them ahead of time can really assist you in being able to answer them intelligently. You should also make sure that you research the company carefully, so that whenever you are asked specific questions about the company you are able to answer them without hesitation. Finally, one of the more important and often overlooked job interview techniques is to make sure that you understand when and where the interview is going to take place.
