Resume database is not universal in China. According to the relevant public information, due to the differences in recruitment needs and industry development in different regions, enterprises in different industries and regions often have different job backgrounds, job requirements, recruitment processes and recruitment standards, which also leads to different information stored in resume databases in different regions, so resume databases may not be universally used. Its scope of application is indeed related to the recruitment process and business needs in different regions. Although some recruitment platforms or human resources service providers provide nationwide resume database services, not all recruitment or human resources service institutions will use the same resume database system or software.
