Top Tips
Use 10-12 size font for the body text, up to 14 for headings, up to 18 for your name on the first page.
Write in active voice instead of passive voice.
Frequently update your CV. More recent experiences are better, but you can also dig further back into your history for meaningful and relevant experiences.
