I don't want to sound overly promotional, but we have a tool for finding higher quality candidates on LifeGuides.me.
Right now we have lots of 20-35 year olds using our guides to understand the different career paths they can take. Recently, we launched a bunch of tools for companies to attract talent on our site.
Basically, we'd interview a few of your employees, write up the content, put it on the site, link to your careers page and give you analytics into who is looking at your content with the ability to message them.
