Throughout my adult life, I have been advised to keep an up to date CV spanning no more than 2 sides of A4. My current CV resides electronically on my portfolio website, alongside my work.
Concise yet informative, my CV has been written in an attempt to convince an employer that I have a strong education and a breadth of work experience in a number of relevant fields.
In terms of layout, four simple sections contain enough information to allow a potential employer to decipher whether or not I am a viable option for their requirements; contact, education, skills, and employment.
