Abstract
Businesses increasingly rely on human capital as a sustainable competitive advantage in order to compete in an economy characterized by continuous turbulence. Based on HR marketing practices in the digital age, they continue their quest to attract, recruit and retain high-potential candidates capable of generating the desired competitive advantages. The objective of this research aims to understand h network sites (SNS) in order to attract potential candidates, retain recruits and limit turnover. To address this problem, a multiple case study was carried out with managers from four call centers.
