You can usually tell when you are being lied to, and interviewers are the same. Even if you don't get caught in a lie in the interview, if you get caught after you get the job, you will probably be fired. Employers want to know what tasks you will be able to handle in the future. They don't care as much about what you did in the past. So don't let the language in your resume be so specific or literal that you loose sight of this.
Some people use long sentences, and some use short phrases.
Which ever you choose is acceptable, however make a deliberate decision to use one or the other, and be consistent thoughtout your resume. Try to avoid long lists of items or experiences. Apples not apple's, dogs not dog's, climates not climate's. Underlining, dashes, bullets, capitalization, italics or boldface type can be used for emphasis or design, however overusing will detract from the resume. Inc. Re-usedby Permission.
