Great jobs, world class jobs, jobs people kill for... those jobs don't get filled by people emailing in resumes. Ever.
When I was younger, I was obsessed with writing the best - which was equivalent to comprehensive, 5pages-long - resume. I landed my first gig in advertising with that resume - which I couriered 24hours to an ad agency in Manila. I did get a call within 48hours and offered the job within the next 24hours. I guess the A's and B+'s in my Philosophy, Theology, Chemistry, Anatomy, Maths, and other classes (I gave them a copy of my grades... to be sure - hey I was desperate!) made a difference.
These days though, more and more people rely on what they have heard of you.
That is until you shift industries.
