The answer is; a well formatted, comprehensive snapshot of your career to date. Accompany this with a profile detailing your aspirations and brief background of yourself; relate this back to the role and then a quick insight into you’re employment history, educations and accreditation. That is all it takes, just a brief demonstration of you as a potential employee. If the role is right, you will get the job. Your CV is a point of introduction and hopefully the first point of a very long and successful career.
