The reason why you are asked to fill in the information of relatives is to check whether you are relatives when you are in the company, because the middle and senior management positions in some companies are sensitive, and it will be inappropriate if relatives work together. On the other hand, if something urgent happens, you can contact them as soon as possible (of course, if you violate the rules and regulations in the company and then run away by yourself, the company can easily contact them through the information of your relatives, so as to know your movements). It is more straightforward and simple to fill in identity information, that is, to know your place of origin, age and other information, and it is also convenient to verify whether you have a criminal record. Of course, if you violate the rules, you can also find out through your identity information.
In addition to the above information, many companies also require your past superiors, colleagues and HR contact information in one or two companies. On the one hand, the purpose of doing this is to facilitate your background investigation, on the other hand, you can collect more information about people through these materials, and maybe you can dig them into the company in the future.
As for your concern about the disclosure of your resume, I can say so, but any formal and reliable company will definitely not take the initiative to disclose it, but in fact, there is no airtight wall in the world. So we will find that our personal information will be leaked anytime and anywhere. The phone calls you often receive to promote insurance, wealth management products, houses and cars illustrate this point.
Why do you need to fill in family members in your interview resume? In fact, it mainly depends on whether you have any relatives working in our company and whether your family agrees with our company. If you don't have relatives in our company, it depends on whether you have relatives in a competitor's company, whether it will infringe on the company's rights and interests, or whether you have relatives in related companies, whether it will involve interest disputes.
