According to a recent NYT article, more and more companies aren't just "googling" their job candidates, they're also checking out social networking sites like MySpace and Friendster:
Many companies that recruit on college campuses have been using search engines like Google and Yahoo to conduct background checks on seniors looking for their first job. But now, college career counselors and other experts say, some recruiters are looking up applicants on social networking sites like Facebook, MySpace, Xanga and Friendster, where college students often post risqué or teasing photographs and provocative comments about drinking, recreational drug use and sexual exploits in what some mistakenly believe is relative privacy.
When viewed by corporate recruiters or admissions officials at graduate and professional schools, such pages can make students look immature and unprofessional, at best.
Remember, the web is not a private place.
