If I apply for a job and send a CV by email (the expected way), but I believe that mailing paper resumes has some advantages as well - it's an actual piece of paper after all, someone can leave it on their desk and take a second look later on, or grab to skimread it on lunch etc....
So, the question is: if I send my application both by email and traditional mail, applying for the same position twice in a certain sense, should I specifically mention it in both applications?
