I have been trying and dying to complete this particular challenge. I tried installing packages, modifying the fields (candidate and position). I tried all the possible combinations that are list on the community page but no luck with that. Then I raised a case and got a response from salesforce team which is to sign in for a new org instead I would call it a special org which already contain Job Application and its fields. You need to access this link https://trailhead.salesforce.com/content/learn/modules/data_security/data_security_org
under this "Sign Up for a Developer Edition Org" there will be first option that says.
- Sign up for a free Developer Edition org with sample data.
Please let me know if this works for you as well. Let's help each other.!!
