Be careful what you post! Here are the social media mistakes that can cost you a new job

What may be even more surprising is that 57% of employers who do social media research say they’ve found content that caused them to NOT hire candidates, the national survey of more than 1,000 hiring managers and HR professionals found.

  • Posted provocative or inappropriate photographs, videos or information: 40%
  • Posted information about them drinking or using drugs: 36%
  • Had discriminatory comments related to race, gender, religion, etc.: 31%
  • Linked to criminal behavior: 30%
  • Lied about qualifications: 27%
  • Had poor communication skills: 27%
  • Bad-mouthed their previous company or fellow employee: 25%
  • Screen name was unprofessional: 22%
  • Shared confidential information from previous employers: 20%
  • Lied about an absence: 16%

Employers aren’t always digging for dirt. They may be looking for information to support a candidate’s qualifications for the job, see if the candidate has a professional online persona or check what other people are posting about the candidate.

But this is a good reminder to use common sense and think about how what you post can have serious long-term consequences.

According to CareerBuilder, you shouldn’t expect social media monitoring to stop once you’re hired. Nearly half of employers (48%) say they use social networking sites to research current employees.
