Human resource specialists usually don't need much knowledge of human resource management, and the knowledge they need can never be made up overnight. If you want to win the interview, I suggest you pay more attention to showing rational thinking, rigorous logic, excellent management and teamwork skills, as well as carefulness and patience. These are the core characteristics of human resources practitioners.

If you are a fresh graduate of a non-related major, and you are in contact with this industry from scratch, I suggest starting with the introduction of human resource management and fully understanding the functions of this industry.

If you are a fresh graduate of related majors, you can find some reference books, such as books with rich management tools, to broaden your horizons. I borrowed a thick translation of human resource management from the library when I was at school, which benefited a lot.

If you are a non-related major, you can start with books on management and recruitment training, such as From Excellence to Excellence, Organizational Behavior, and Human Resource Management Practice.
