In answer to your questions:
1) There is no social login functionality built into the theme, however it is possible through use of plugins such as those mentioned on our
recommended plugins page.
2) Users can register as a job seeker or an employer/recruiter
3) They can subscribe to RSS feeds for all listings, or ones in specific categories
4) Accounts have their own profile page as is shown on the
JobRoller demo site
5) Not really sure what you mean, but in terms of user accounts, you can only register one per email address
6) You would need knowledge of mysql admin for this as there is no built in importing tool for this purpose at this time
7) This is not a feature of the theme
8) Yes you can view this from the J
obRoller demo
9) Yes, admin is notified of new listings. Thanks.
