You dont get jobs on there because unless you have a “god tier” resume and application filled out, HR has to pay to unlock your name from your application, so nobody is going to do that if you arent the #1 candidate in all of LinkedIn that applied.
I'm using LinkedIn ATM (searching for a new job) and all the jobs I've applied for have gone off site to the company's own applicant submit site. So I don't get what LinkedIn is actually locking up?
It is advertised as a necessary evil; "everyone needs one for employment"
I recently deleted my LinkedIn. It is just used to data mine information from you. I think the site is generally pretty useless, even without all the privacy concerns.
