The majority of employers still use an interview as part of their recruitment process. These days this could be either face to face or via the telephone. Here are a few tips to help you prepare yourself adequately:

Take the time to review the "standard" interview questions you will most likely be asked. Also review sample answers to these typical interview questions.
Then take the time to research the company. That way you'll be ready with knowledgeable answers for the job interview questions that specifically relate to the company you are interviewing with.
