An interview is the next stage of a job seeking process. If you have reached this stage it means your resume/CV has achieved its goal. Many people mistakenly believe that a resume is successful only when it lands you a job. Nothing can be further from the truth. A resume alone was never meant to grant you employment. Instead, it is meant to get you through to the next stage – an interview appointment. 
You can have a great resume with every little detail polished up to perfection, but never get what you want in terms of employment. And vice versa, you can have a run-of-the-mill resume with needed skills and experience, but get hired after the first opportunity. What do you think the difference is? Interview! Depending on how you do during an interview, you can either downplay your weaknesses on a resume by demonstrating your professionalism or you can diminish your high-quality writing while giving the wrong answers during an interview.
Be Prepared. If you have received an interview invitation and really want to make use of such an opportunity to get a job, then you have to be well prepared to prove your professionalism. One thing you have to know about interviews is that they can get very stressful. In fact, the vast majority of interviews are meant to be that way in order to see how an applicant responds to stress (which is likely to occur almost at every workplace in one form or another). - First and foremost, one has to realize that there are no details that don’t matter. Each and every detail can play to your professionalism… as well as play against you. So when preparing for an interview there should be no things that don’t matter much. Personal hygiene, punctuality, and business attire – all of these can tell more about who you are than all of your accomplishments and skills on a resume.
Secondly, do your homework. Make a research on the applying position and the employer. It is vital that you have a clear understanding of where you are going. The knowledge of the company and position will boost your confidence since you will know what you will be dealing with.
Thirdly, you have to be ready to answer tough questions. This is the hardest part. Of course, you won’t be able to know what questions are going to be asked, but you surely can prepare yourself by searching some of the tough interview questions on the Internet. There are questions that are asked almost during every interview so knowing at least one answer can give you an advantage. The key to answering tough questions is to listen carefully. Many people make a huge mistake when they hurry to answer. Remember, you have to understand what is being asked before you ever start answering. There is absolutely nothing wrong if you ask an interviewer for clarifications. All of the answers have to be concise and clear.
Lastly, we recommend sending a thank you letter in order to re-emphasize your interest in the position. This will help employers understand that you really want this job, which is very important (who wants to hire someone who is not interested/motived for a job).
