It's pretty simple (because many recruiters don't do it): feedback. Why didn't they move forward, and where could they have done better? Most people are very content when they receive non-generic feedback. Most importantly: it's not Halloween, so enough of the ghosting!!

Maintaining positive relationships with candidates you’ve had to turn down is a strategic investment. It enhances your employer brand, expands your professional network, and builds a pipeline of potential future talent. By treating every candidate with respect and consideration, you create ambassadors for your organization who carry forward a positive message about your brand.

Recruitment is all about right networking. To nurture positive relationships with candidates you’ve rejected, I would suggest that one should maintain open communication and express genuine appreciation for their time and effort. Offer constructive feedback and suggest ways they might strengthen their profiles. Stay in touch by sharing relevant industry insights, job openings, or professional development resources. Personalize your follow-ups to keep them engaged and remind them of their value. Building a supportive network can turn past candidates into future advocates and potential hires.

Giving feedback is an art. When done correctly, it not only avoids damaging relationships but can actually strengthen them. Keep in mind that finding the right fit is a complex process, and a mismatch isn't always the candidate's fault - sometimes, the role simply isn't the best for them. Approach the conversation with respect, and use it as an opportunity to explore what other roles might be a better match in the future.
