A resume should be seen as a personal visiting card. You are solely responsible for the content and the way you present it. The main guideline for building and updating a resume is that it represents your career profile in the best possible way. Do not only update the job titles and employers, but also describe the relevant content of the jobs and education/ training that you have had and make sure that your skills, personality and interests are clearly defined. Personal details, education, work experience, skills and personal characteristics or interests are the main ingredients of a good resume. And updating should be done on the basis of relevance, which can change at any time in your career.
