In answer to your questions:
1. Yes, job seekers can set up job alerts
2. Job applicants can attach a resume to the online application form, but by default, the resume information on the site entered in by the job seeker is not available as an attachment. You can however, find this functionality in the form of an optional add-on called
FXTender Pro
3. Views are visible near the bottom of the job listing page as seen on the
JobRoller demo site
4. AppThemes doesn't offer customization services, however we do have a
certified partners page where you can find developers for hire. Thanks.
