10 Things that Scream, "Don't Hire Me!" Red flag No. 1: You don't have any contact information on your résumé When you're crafting your résumé, you should focus on highlighting relevant skills and accomplishments that are in line with the position for which you are applying. But what good is an impressive résumé if hiring managers have no way to get in touch with its owner? If they can't find you, they can't hire you. Always provide a home address, phone number or e-mail address so employers can get in touch with you easily. Red flag No. 2: You have long gaps between jobs on your résumé Even if your long departure from the work force is valid, extended lapses of unemployment might say to an employer, "Why weren't you wanted by anyone?" Gimbel says. Anytime you have more than a three-month gap of idleness on your résumé, legitimate or otherwise, be prepared to explain yourself.
