There is an old adage about writing that goes something like “show, don’t tell.” The idea is that good writing shows what the author wants to communicate, and through showing lets the point communicate itself. Bad writing tells the reader things. Writing resumes is the same way. You don’t want to say what you are. That is telling. You want to say what you did, which is showing. There’s a big difference. The job search is all a numbers game after all.
