Legal analysis: 1, remain relatively objective. When evaluating candidates, the interview will also call the person in charge of the relevant parallel lines, which is objective and relatively fair, just like the subjective questions of the college entrance examination, especially the composition, which requires many people to take the average. Similarly, for a person's assessment, everyone will have some subjective colors. 2. Ensure comprehensive quality. Because some large companies have a fixed period of time to recruit people in the early stage, the recruitment channel will be closed after the time period. Sometimes, business leaders may lower some requirements because of the urgent need for employment. Cross interview will ensure the comprehensive quality of the recruiter's choice to a certain extent. 3. Avoid favoritism. Where there are people, there is a chain of relationships, especially in the company. After many companies change their business leaders, the new business leaders will recruit people again. At this time, I will bring my former cronies in. If there is no cross-interview, does it mean that a person can come in casually under the idea of the business leader, and a better candidate will be defeated because of the relationship?
