Think carefully before you eliminate any. For example, you may be interested in banking and one of your jobs was taking orders at a counter of a fast food restaurant. You bet there is. You can generalize from this example. Look for experience which involved interpersonal contact, a factor common to all jobs.
Activity is expressed by verbs.
Action translates freely from one job to another, though the topics or things you acted upon may not. Does better work than is expected Is courteous Gets along with fellow employees After selecting experiences to use in your resume, write a first- person description of each one. Editing will follow later. Start with the one you believe is your best and describe what you did, in the first person. Length should not be a concern to you because this will not be the finished product.
