Why a link beats a PDF attachment
Emailed attachments get mangled. Some corporate mail filters strip or quarantine them, LinkedIn messages don't accept files at all, and application portals often re-render your PDF into a preview that clips margins or drops your header. A link sidesteps every one of those: the recruiter clicks and sees your resume rendered cleanly in their browser, exactly as you exported it. It also survives being forwarded, when a recruiter passes you to a hiring manager, the link travels intact instead of becoming a 'see attached' with no attachment.
