Recruiters are already adapting Facebook as a recruiting tool: A 2012 Jobvite social recruiting survey notes that Facebook saw the biggest gains in social recruiting. A couple key findings from the survey are as follows:
2/3 of recruiters use Facebook to find new talent, a growing trend since Facebook saw the biggest gain in usage, jumping 11 points from last year to 66% in 2012.
For the first time, more than half (54%) of recruiters now use Twitter for their talent search, revealing the importance of watching what you tweet.
LinkedIn remains the dominant recruiting network, used by 93% of respondents. (87% in 2011 and 78% in 2010).
Pair previous recruiting activities on Facebook with social search and this equates to more competition for Linkedin. Linkedin's recruiting platform is expensive, and any competitive threats could further squeeze already tight margins. Further, the fact that Linkedin has already reached most corporate recruiters begs the question as to where the implied growth will come from in the long term.
