Clear and concise. Those two words are what perfectly describes an effective resume design. One way in creating such a design, is by having each section of your resume short, but filled with a lot of information.
Because of our modern digital age, most readers want a style of writing that can be well-understood, and presents a complete thought within just a short amount of text. Readers will most likely, lose interests once they've reach of fifth line of text and still don't have self-contained message to take from it. To avoid this scenario, make each paragraph and section of your CV short, but dense with information. Break down complex parts, into smaller, bit-sized pieces that can be easily digestive by your potential employer.
