How to make a resume effective?—That's simple, all you need is to write your resume in such a way that it can present all your information in clear and comprehensive manner.
A major factor in writing a good resume is by making it clean and simple. Make sections of your resume short, but substantial. Use professional looking fonts (e.g. Seriff fonts) and limit your font size between 11-12, this makes the segments of your resume more pleasing to your potential employer's eyes. Also, be positive—write the content in your resume in an optimistic manner. Leave out negative information that is irrelevant to your core argument (e.g. Why should they hire you)
