One of the things I do on an ongoing basis is help maintain the job applicant system at the office. A couple of trends continue to amaze me. First of all if you're submitting a file giving it the name "resume.doc" is a sure-fire way to make sure your resume will get lost, messed up and never make it to where it needs to be. A second great way to cause problems is to put special characters in the file name. Calling it "Joe's Resume.doc" or "resume/web-2010.pdf" won't help you win friends either.
So here is a simple idea. Keep the name of your files descriptive and use only letters, numbers, dashes and underscores in the file name. The newspaper says there are a few folks out there looking for jobs these days. You don't want to miss out on the interview just because the folks trying to read your resume can't find it amongst the piles of submissions.
