In todayand‟s world, every company is in competition in the search for talents and so is the individuals are in search of good employers. The big question here is - why should an individual specially Gen Y and Millennial will choose to work for a company rather than another? Another issue about current generations is that teenagers and young adults at the beginning of their working lives are more focused on the brand. They want to work for a Google or Infosys because they have bought into the brand emotionally. Thus, todayand‟s IT/ITeS firms have not just competition for customers but also for the quality people, in the whole employment market. The best way to do this is by having a clear, identifiable employer brand and communicating it in the marketplace. In the same way that a corporate brand aims at attracting and retaining customers, so an employer brand aims at attracting and retaining employees. The present research aims at examining the impact of employer branding in the modern digital Economy leveraging Social Media, Mobile, Analytics and Cloud (SMAC) on attraction of prospective employees who are millennial (Gen Y) as well as retention of existing workforce of different generations (e.g., Baby Boomers, Gen X and Gen Y) in top ITeS organizations in India.
