The disadvantages of external recruitment are

External recruitment means that enterprises recruit talents from outside in order to fill job vacancies. Although external recruitment has some advantages, such as introducing new ideas, new skills and new experiences, it also has some disadvantages. First, the cost of external recruitment is higher. Enterprises need to pay advertising fees, recruitment consultant fees, interview fees and other expenses, but also need to spend a lot of time and energy to screen and train new employees. In contrast, the cost of internal recruitment is lower, because the enterprise already has the files and evaluation information of internal employees, and at the same time, the internal employees are already familiar with the culture and process of the enterprise. Secondly, external recruitment may affect the cohesion and morale of enterprises. If internal employees see that enterprises frequently recruit external talents, they will feel that their work value is questioned, thus reducing morale and loyalty. In addition, it takes some time for external employees to adapt to the culture and process of the enterprise, which may also have an adverse impact on the cohesion of the enterprise. Finally, external recruitment may lead to a short stay for new employees. If the enterprise does not provide enough training and development opportunities, new employees may leave the enterprise soon, which will lead to job vacancies. In contrast, internal employees are already familiar with corporate culture and processes, and usually grow and promote gradually under the training and development opportunities provided by enterprises. To sum up, although external recruitment can introduce new ideas, new skills and new experiences, it also has some shortcomings, such as high cost, affecting cohesion and morale, and short staff stay. Therefore, enterprises should comprehensively weigh all kinds of factors and flexibly choose internal recruitment or external recruitment according to specific conditions when conducting hiring decision.
