Thank you for replying to the question but it didn't help me. I am not allowed to login to this page. The trailhead link does not have the RecrutingApp-9.0. zip file. I am learning Salesforce and in the book that i am using they asked to download this zip file to work with the exercises. Unfortunately the link in the book is not valid anymore.
Ih has the link to the recruitment app.
Nevertheless, here's the direct link, https://isrovita-dev-ed.lightning.force.com/packagingSetupUI/ipLanding.app?apvId=04t0P000000N9rs
