Greg Savage says that 75% of candidates on LinkedIn are not looking for a job. Add to that, according to LinkedIn only 24% of their members are considered active users of LinkedIn. 

So only a quarter of the just over one million LinkedIn members in Thailand will read the news, will see your vacancy postings and check if anyone sent a LinkedIn mail.

In the old days, hiring companies relied heavily on recruitment firms' databases when they were looking for people. That is obviously not really necessary anymore, as access to names have become so much easier with the internet, the job boards, LinkedIn and what have you. 

For sure, recruitment companies who go shopping in their own database and post ads on the job boards are a dying breed. 

Recruitment is not a resume race anymore. It’s a talent acquisition business.
