To start your resume, begin with determining your objectives (do this prior to writing the resume). Clearly state what sort of a job you want and you should know what kind of skill-set and experience is needed for that job. After your objectives are determined, prioritize the content of your resume to suit those objectives. A lengthy resume does not necessarily translate to higher qualification. While your resume is essentially a marketing tool, it shouldn’t read like one. Avoid over-use of industry jargon. Be factual, concise and mention specific achievements. You don’t need to go into detail about every accomplishment in your resume, however as companies are looking for something more than just training and education, you need to project a proven track record.
Important: the interview is the place to elaborate on your accomplishments, not the resume.
