Step-by-step explanation:
In a company with a polycentric orientation, host-country nationals are likely to be employed in the selling situation where there is a need for deep understanding of the local market, culture, and consumer preferences. These individuals are natives of the host country and possess valuable knowledge and connections that can help the company effectively market and sell its products or services. For example, a multinational company selling consumer goods in a foreign country may employ host-country nationals as sales representatives who can communicate fluently in the local language and have a strong understanding of the target customers' buying behaviors and preferences.
