Follow these few steps to dramatically improve the quality of your CV:
Keep it simple, uncluttered and in an easy-to-read font (on plain white A4 paper).
Keep it free from unnecessary details (e.g.: don't write lines upon lines for your interests!)
Keep it free from spelling/grammatical errors - maybe ask someone to proof read it.
Check your personal details - sound obvious but it does happen (wrong phone number etc).
If you have a job spec - match your CV to this to ensure you have included relevant skills.
Believe it or not - there is no perfect CV. Just concentrate on making use of the kind of CV design that suits you best - chronological, functional or a combination of the two.cv examples uk
