Of the top social networks for recruiting, 94 percent of recruiters said they used LinkedIn, followed by 65 percent for Facebook and 55 percent for Twitter.
Research firm Research and Markets said in a global recruitment report last month that job applicants are also increasingly using social media to network and identify employment opportunities.
"What we've seen is an increase in background checks. So a third party is hired to check everything - go through qualifications, check previous work history, check activities," said Andrew Tomich, executive general manager for recruitment firm Hudson Singapore, in response to a question about whether there was greater use of social media by employers to assess potential candidates.
"I think in some situations, organizations are using social media to assess someone. It's a big thing if you are in a public facing role," he added.

Watch what you say
Indeed, what somebody says on social media can have ramifications for their current or future employment.
Justine Sacco was sacked as communications director of New-York based internet firm InterActive Corp last month after sending a tweet before departing on a holiday to South Africa that linked AIDS to race.
Speaking about privacy at The New York Times' Global Forum Asia last year, Meg Whitman, chief executive of computer giant Hewlett-Packard, had this to say on the subject:
"There has to be some personal responsibility here. When you put things on the internet, on Facebook, on Twitter on LinkedIn, you have to assume that it's almost like standing outside your house with a sign – handing out your information – you have to be really thoughtful about what you put online."
"Companies have a real responsibility to take that data that is near and dear to you, and handle it in a really thoughtful, deliberate way, and use all resources to maintain that privacy," she added.
