CareerBuilder also asked employers why they use social networks to research candidates, and 65% said they do it to see if the job seeker presents himself or herself professionally. About half (51%) want to know if the candidate is a good fit for the company culture, and another 45% want to learn more about his or her qualifications. Some cited “to see if the candidate is well-rounded” and “to look for reasons not to hire the candidate,” as their motives.
