The visual layout of your CV is very important. Even though the wording you use may be correct, if people cannot find the information they want quickly they will move on to someone else's CV. You should have plenty of spaces in your CV with appropriate headings and section breaks.
Organising your CV
If your CV is not well organised then the reader will find it hard to follow and will not be able to build up a picture of you quickly. Remember the reader will not spend very long looking at your CV - so if they cannot find what they want they will not bother to read any further.
Length of CV
Employers do not want to know your whole life story - just enough to decide whether they should interview you or not. Nobody wants to read a ten page CV but contrary to popular opinion you do not have to limit it to two pages of A4. The optimum length depends on your level of experience, for example, a graduate CV should never be longer than two pages. However, if you have over ten years industry experience a three or four page CV is acceptable.
Long paragraphs and sentences make a CV difficult to read quickly. Try to keep your sentences short and punchy. Use of bullet points to break up the text under section headings is often a good idea.
Too little information
A lot of people do not include enough details about their previous jobs and experience and an employer therefore does not have enough information - they will therefore have to reject your application.
Your CV should be carefully checked for such errors before you send it out to employers. Tiny errors in your CV can detract from an otherwise good CV and make you look lazy or careless - not the sort of qualities you want to portray to an employer. As you will probably be 'blind' to these errors you should get someone else to check your CV for grammar and spelling errors.
