Although you may watch what you say or do on Facebook because of your job (Tell me about IT!) it still may give your employers more information about you than you originally thought.

Researchers from Northern Illinois, the University of Evansville, and Auburn found that looking at people’s Facebook pages for just ten minutes could predict how well they’d do on the job.

They had people in Human Resources look at the Facebook pages of job applicants and grade them on traits like intellectual curiosity, conscientiousness, agreeability, and whether they were extraverted.
