Check this out - re:Work by Google

I just heard about this from the StartUpHR community, and wanted to share! It's especially usefully for organizations that don't know where to start with their HR/People Operations.  The website provides guides on topics such as Hiring, Analytics, and Management- with detailed steps and relevant case studies. These are all based on hiring trends and findings from Google People Ops Team.
