1. Company business development: With the expansion of the company's business scope and the development of new projects, more people are needed to meet the new job requirements. Therefore, companies need to recruit more people to support these new business needs.

2. Turnover: The company faces a certain turnover rate, so it needs to constantly recruit new employees to supplement the positions of former employees. In order to ensure the continuity and stability of the company's business, the company needs to continue to recruit to maintain a sufficient number of employees.
