Most companies won't give applicants tips for how to get their foot in the door. They treat the application and interview process like it's something the Skull and Bones Society would have locked away in a vault.
I was blown away by the career page on razerzone.com. The folks at razerzone.com give you tips for how to get your cover letter noticed ("It's both your chance to show us that you understand the position you're applying for and your opportunity to explain why you'd be a great fit") and show a considerate understanding of difficulties some applicants might face ("Razer understands that showing code from past professional work due to confidentiality requirements may not be possible, so find some things you can show us").
A page like that should be a requirement for company web sites. Not only is it a considerate thing to do, but it could help streamline the efforts for hiring managers exponentially.
