Always think of your resume as a marketing brochure, never as a duties and responsibilities list. Your resume must market you towards a specific position and show how you have been of value to your past employers. It is never just a general career document. Remember, companies look for keywords and key phrases that relate to the position they are hiring for, and the explanation of how you used those skills, software, competencies, career-related acronyms, etc., in your bullet points under each position. To your job search success!
