Study your CV prior to your job interview and indentify areas of your work experience that is specifically relevant to the job that you are being interviewed for. Be sure to scrutinise the job advert as this will guide your answer and provide you with clues on what exactly the recruiter is looking for in a candidate. Your answer should be concise and relevant; the recruiter has already seen your Curriculum Vitae and already has a good idea of your experience. Try to get the recruiter to specify what areas they would like you to discuss so as to avoid digressing off the topic with long winded explanations. The reason why the recruiter is asking this question even after having seen your CV application is because they want to hear how you would describe your experience verbally and to ensure that your verbal explanation is consistent with the information detailed in your CV.
