In the short term, you should tweak your resume based on each job you apply to. For example, if one position you’re applying to seems to weigh a certain responsibility or focus over another, you should be sure your resume conveys your expertise in this area. At the same time, you should be updating your resume with your experience as it develops, adding any new skills you’ve learned, courses you’ve taken or awards you won.
An effective resume lays out a summary of qualifications that will push the hiring manager or employer to move forward and invite you to interview for the position. As well as details on skills, education, and work history, resumes can also have optional sections, such as an objective, summary statement, skills, or career highlights. Those sections can be added after you’ve compiled all the factual information you need to list on your resume. For many people, it can be helpful to sit down with a pen and paper, or a blank Word document, and jot down their work history from start to finish. Of course, if you have been in the workforce for many years, this is not going to be time-efficient, so you may choose to focus on your most prominent and relevant positions.
