Most job applications from that I know are sent by email. Making linked PDFs available for download via http should make sense for this.
If someone is handing out a job application, that's still going to be printed on paper in most cases.
But why don't you include all pages in one PDF without linking? If you scan and edit all documents properly you can make a good quality grayscale 10 page PDF that has about 1MB. A hyperlink needs to be clicked, for external links usually a message will pop up, asking if you trust the link... Would you trust a link someone unknown sends to you? Maybe linking is not the best strategy for common job applications. Sure, there might be exceptions. Internal document linking to mentioned topics/qualifications could make more sense and no security warning will pop up either.
