Candidates are looking for feedback on what they can do better. HR doesn't want hiring managers to form opinions on that. HR wants (as near as possible) objective feedback on whether candidates meet a hiring bar, and for a hiring manager to select amongst those that do choose the best candidate. Ideally, they want you to make sure you're making serious consideration of candidates in under-represented groups in order to show commitment to DEI targets.

Oftentimes, the reasons why candidates don't get selected come down to things like "you exaggerated your involvement in a key project and we figured that out during the interview" or "you're fine, but we found someone we liked better".

How do you think honest feedback of "you should stop providing misleading descriptions of your work experience in your resume" goes over?
