Check Your Privacy Filters: Facebook Wants To Be the New LinkedIn (cnet.com)
From a report on CNET: Facebook isn't just for wasting time in the office. It can now help you find a new job entirely. The social network has unveiled a Jobs page, which allows businesses to list all kinds of work for you to find. You can even apply for the job and make contact with recruiters directly through Facebook. This could be seen as a challenge to competing services such as LinkedIn, the recruiting network acquired by Microsoft last December. But while LinkedIn is entirely focused on business, Facebook's social aspects could make it easier for potential employers to trawl your profile for details of your personal life.
I don't have a Facebook account. But I do have a LinkedIn account with 800+ connections to recruiters I've talked to or worked with over the last 20+ years of my technical career.
Which one will get me a job? Neither.
Out of all the job search websites out there, Indeed is probably the best one. Especially if you can respond to a job posting within 15 minutes of it being posted. I've gotten many phone interviews and two job offers that way.
