Writing skills• How to write a resumeTips:

Capitalize the headings to make them stand out on the page.

Condense information, use phrases and clauses rather than complete sentences.

List your most recent education and employment experience first and then work backward so the employer can quickly gauge( 评估） what you’ve done recently.

Don’t try to cram （塞） too much material onto a page. Ample （扩充） white space is important.
