How Often Do HR Managers in Healthcare Rely on Job Portals for Recruitment?

I would like to know the rate of use of job portals for recruitment by HR managers in the healthcare industry.

Well, I guess job portals are the commonly used medium for recruitment in any firm, whether it's healthcare or any other. However, references and advertisements do play a part. Most companies opt for job portals, and they do look out for vendors (recruitment agencies) to fulfill the requirements.
