Dear Sathya,
Headhunting is the process of approaching people working in the same industry whose profile matches the position you are recruiting for, even if you don't have their direct contact details. You need to identify the most suitable candidates for the role and then reach out to them, whether through Social Networking Sites, the phone number of the company they work for, or other sources. People often confuse the terms "Referencing" and "Headhunting," but referencing is just one aspect of headhunting. If you have any more questions or need further clarification, please feel free to ask.
Regards,
