Can the recruitment software see its own employees? Is it safe?

As you can see, there is nothing unusual about this function. As long as you update or log on to these recruitment websites, I will search by company name or other keywords, and the system will list all resumes according to the latest time (excluding name and contact information). If it's from our company, I don't need to download it (deduct money). By comparing the internal information with work experience and education experience, it is easy to know who has recently updated their resumes or logged on the recruitment website, which may be job-hopping.

However, there is another function of these recruitment websites, that is, employees can set blacklists in the background, so that resumes will not be searched by employers.
