While without a doubt the internet has made it easier to search for jobs-from such general job-seeking sites as Monster.com to more specialized ones such as JournalismJobs.com-it has also, in some cases, made it more difficult for someone to get hired. According to a survey released in April by CareerBuilder, LLC, nearly 2 in 5 companies use social networking sites to research job candidates. And a March survey from Eurocom Worldwide shows that 1 in 5 technology industry executives admit to rejecting an applicant based on his or her social media profile.
