A passive infrared sensor (PIR sensor) is an electronic sensor that measures infrared (IR) light radiating from objects in its field of view. They are most often used in PIR-based motion detectors.
Recruitment (hiring) is a core function of human resource management. It is the first step of appointment. Recruitment refers to the overall process of attracting, shortlisting, selecting and appointing suitable candidates for jobs (either permanent or temporary) within an organization.
Full cycle recruitment, or full life-cycle recruiting, is the process a recruiter uses when placing a candidate. The process begins when the job order is taken and ends after the new hire begins his new position. More companies are requiring full cycle recruiting as it lowers turnover and reduces the cost of hires.
