As a recent graduate (actively looking for a job) I have been using LinkedIn for a while, and I am very disappointed.

I get around one response per 50 applications I send via the platform.

Recruiters don't classify their posts correctly, so when I search for "entry-level" positions, I get mostly positions that require 5 years of experience, or just list all possible web technologies so they land more search queries, etc...

Example : I search for a position with PHP/JavaScript listed as technologies. Then when contacted by the recruiter it turns out to be a JavaEE position, but "knowing PHP and JavaScript is a plus".

I'd close my account if I wasn't this desperate.

Edit: Added example
