The information in a
CV can be divided into several parts. By clicking
on each of those you will access forms that
you can fill in and print your own CV afterwards.
If you leave any parts or boxes blank (if
you have nothing to fill in, or if you think
it could be harmful in the eyes of an employer),
they will just not appear in your CV.
Of course you don't have to use the printed
CV directly for an employer: you can write
or type it out again with additional improvements
of your own. But avoid making an essay of it.
