How do you maintain confidentiality in job details during the recruitment process?

As a healthcare recruiter in the Middle East specializing in medical staff placements, I often encounter candidates who immediately ask for the name of the hospital and additional specifics. While I strive to be helpful, I prefer not to disclose the hospital’s name as it could lead candidates to approach the facility directly, bypassing my services. I’m looking for strategies to navigate this situation effectively. Any advice would be appreciated! Thank you.
