DON'T use multi-colored text or too many different font sizes. Italics, underlining, shading, graphics, and vertical/horizontal lines or boxes are also best avoided. DO keep your CV length to a minimum – two or three pages is ideal. Print in black ink, on one side of each sheet of A4 size paper, and choose fonts like Verdana, Arial, Calibri or Times. DON'T include personal details such as your date of birth, marital status or photo (unless you are applying for a job where these are relevant). DO include a link to your website, if you have one (and if it's related to your work). Whether it's a website or blog, or a Twitter, LinkedIn or Instagram account, an online presence can really boost your image and get you taken more seriously, especially for careers in the media, creative industries and IT. DO, wherever possible, quantify your achievements. If you can say, for example, increased sales by $50,000, reduced turnover by 34% or increased website traffic by 125% rather than making a more general claim, that will give your assertions more weight and clarity. DON'T use a PDF format for your CV, especially for less IT-heavy industries, as some software won't be able to read it easily. Most companies prefer Word (.doc/.docx) files wherever possible. DO use testimonials from previous employers. Consider adding them to your CV as hyperlinks, linking them to an employer testimonial on your LinkedIn profile or website (if you have one). DO proofread and spell-check – and check again. A recent CareerBuilder survey found that 58 percent of CV contain typos. Make sure yours isn't one of them!
