Ask any of your schoolmates or friends if they know what a CV is. They probably have an idea but not so many of them know how to write one. Today, there are many books in bookshops around town that help in CV writing. This can be a good start. I indulge in writing CVs for people I work with at times.
Reviewing people’s CVs and making relevant changes can increase their chances of getting employed. A lot of people abroad edit CVs for a small fee. If you normally use the., internet, you can search for Agencies that deal with CV writing and customization. You will be shocked to realize how big the CV writing industry is.
