According to a recent survey by CareerBuilder.com, one in four managers (at least in the US) check out future employees by searching online. And 51% of them said they chose not to hire someone because of what they found. They were then asked what kinds of information they found online that caused them to rule out a candidate. 31% of candidates had lied about their qualifications, 25% had poor communication skills, 24% were linked to criminal behaviour, 19% badmouthed their previous employer or colleagues, 19% posted about drug or alcohol use, 15% shared confidential information about a previous job, 12% lied about an absence, 11% posted provocative/inappropriate photographs, and 8% used an inappropriate screen name.
