Excerpt from Internet Your Way to a New Job, How to Apply for Jobs Online
There isn’t any room for guesswork in applying for jobs online. It’s really simple. Follow the instructions in the job posting. Companies think less (or will ignore) applicants who don’t follow the instructions. If the listing says send a cover letter, write one. If the listing says apply online at JobDig, do so. When the help wanted ad says send a PDF, don’t send a Word document.
