If there’s any small solace when starting a job search in this recession, it’s the proliferation of digital technology to help you re-enter the working world. Web sites like Indeed.com and LinkedIn.com have multiplied the number of job openings you can track and the professional contacts you can make. Email and smartphones make it easier to pitch yourself and set up appointments. But think twice before picking up that BlackBerry and thumb-typing a message to the hiring manager whose email address you so slyly uncovered online. In the end, landing the right job hinges on old-world skills.
