This is a less traditional CV, but can be very effective. By moving your work experience to a less prominent position on the second page, the focus moves to your transferable skills on the front page.
You can sell yourself really well by matching the skills you select to those required for the job you are applying for, for example, those on the job specification.
It is really important to tailor your CV to each post.
Each skill needs a clear example (some evidence), but this can be taken from your degree, voluntary work, extracurricular activities and employment.
When should you use a Skills based CV?
Usually if you have very little or no directly relevant experience, or if you might be trying to break into a new career, or making a significant change of career direction.
