Every job posting asks for a combination of experience, knowledge, skill, and education. Another way to think about this is "weight." The employer wants to know that you can carry the load of a given job. For example, an entry level job will ask for less weight than one that looks for 3-5 years experience or a background supervising or training employees. In writing your resume or presenting yourself at an interview, you need to be able to show how and why you are qualified to do the job. Look carefully at job posts for positions you are seeking and identify the kind of weight the employer is seeking. Show that you can carry the load.
