Great parties usually mean great pictures, but think long and hard before uploading those photos to your social networking Web page. The proliferation of social networking sites and powerful search engines makes it easy for friends to keep track of you, but friends aren't the only ones who will have access to your latest escapades. A lack of digital privacy also means employers can be privy to information you might not want them to find. According to a CareerBuilder.com survey, 26 percent of hiring managers say they have used Internet search engines to research potential employees. More than one-in-ten admit to using social networking sites in their candidate screening processes. Many of these employers don't like what they find. Fully half of hiring managers who used search engines to research candidates didn't hire the person based on what they found. Of the managers who browsed social networking sites, 63 percent found dirt that caused them to dismiss a candidate. Interestingly, many candidates are far more honest online than they are on their résumés. Thirty-one percent of hiring managers say they have disqualified a candidate after searching the Web and discovering the candidate had lied about his or her qualifications. Other dismissals resulted from: Poor communication skills (25 percent) Criminal behavior (24 percent) Badmouthing previous companies or employees (19 percent) Posting information about drinking or drug use (19 percent) Disclosing confidential information about previous employers (15 percent) Lying about an absence (12 percent) Provocative or inappropriate photographs (11 percent) Unprofessional screen name (8 percent)
