Are the callback personnel newly recruited?

Callbacks are usually regarded as newcomers, but whether they are counted as newcomers may vary from company to company or organization. Generally speaking, the callback personnel are re-recruited from those who have left or been suspended. They are usually rehired to fill previous vacancies. In this case, they are often not regarded as recruits. However, if the callback personnel are regarded as completely new employees, re-enter the recruitment process and sign a new employment contract, then they may be regarded as new recruits. In this case, they will get the same treatment as other new employees.

Due to the different recruitment policies and practices in different countries and regions, I suggest you consult the employee manuals, policy documents or human resources departments of relevant companies or organizations to obtain accurate information.
