Your resume is your sales document. Make sure to target your resume for each job you apply for. It must be simple, concise and easy to read. Most importantly it should mirror the job criteria of the job you are applying for, addressing all of the requirements for the role.
Create a first draft
Write all your qualifications, experience, employment history, personal history, hobbies and interests, including all relevant information under headings. At this stage just write as many pages as you need to get the brainstorming process done - only later on will be concerned with cutting it down.
Filter out the unimportant
You can't tell potential employers your entire history, but you can highlight the important details for them: these will include skills, insights and abilities that you have been able to develop, as well as your academic qualifications and what you gained from your studies and experience.
Keep it concise
Eliminate unnecessary details. HR departments have lots to do, so don't make the mistake of asking them to read through an unnecessarily long resume. Remember that there may be a pile of resume’s a foot high for some positions!
Your resume should be around two pages in length, although it may be longer if you have to describe a lot of relevant work experience and achievements. Even a two page resume is of no advantage if it's full of information that isn't reasonably applicable to the position you're qualified or applying for.
Obviously lying on your resume is a risky strategy, especially about qualifications, and you should avoid any such temptation. Better to be proud and confident of who you are. Integrity and reputation are more important than qualifications. A resume with a lie is an embarrassment, or even a dismissal waiting to happen,
