i would like to get details on scope and limitations of online job portal system

Little more than a decade ago, online job searches were primarily the province of a tiny population of hardcore techies. Today, online recruiting forms one of the central pillars of a smart staffing strategy for firms in every economic sector.

Increasingly, job seekers are turning to electronic resources such as corporate web sites, federal, state, and municipal job postings, online job search engines and aggregators, Internet classifieds, and online versions of local and national newspapers to facilitate the job search process. Conversely, a growing majority of employers have moved a significant proportion of their recruitment efforts online. For professionals on both sides of the hiring equation, the notion of conducting a job search or candidate hunt offline is virtually inconceivable in 2007.
