For the call-centre operators, who are a key element of our human resources, we apply a very intensive strategy for recruitment. It's like a reality-show contest. When we get their CVs, we start observing them, even down to how they answer our phone calls. Their attitude shows from their voices. At the desk of each operator, we provide a mirror for them to observe their own facial expressions. Their expressions are reflected in their voices. So, mirrors help them to be mindful. Then, when the candidates come for an interview they are grouped into seven-person groups and asked to do seven or eight activities. These activities involve letting them express opinions, engaging in teamwork, using their voices, and other skills. They are closely observed by two HR staff.
