In today’s economy, I understand that for many corporations, private firms and non-profit organizations, the HR employees are being trained to use skilled tactics in there hiring procedures and screenings.

What kind of methods and tools the Human Resource Departments use and what kind of training materials they receive and learn in order to select job seekers for today’s markets?
