LinkedIn provides one such platform where you can run a simple search for the profiles of persons with job titles like Recruiter, Talent Acquisition, or HR Manager. You can further use filters like location, company, and industry to get more precise results. Plus, you may explore the People section of the company pages for sourcing potential contacts, participate in job or industry-specific groups, and identify recruiters who have posted the same type of job and reach out to them for an immediate connection.
