The process is still very broken. I've applied for multiple jobs where I've been forced to use a site called successfactors.eu, and the interface leads you to think it's integrated with Linkedin ("apply with Linkedin" button), in reality you're forced to re-enter your CV data multiple times, or the data is all over the place after being imported. I'd much rather send my CV attached as a PDF along with a cover letter directly to a recruiter or HR person.
It's been hit or miss and it gives them a little too much leverage, but it's been effective to some degree.
