I advocate for radical candor. Be direct, even if it feels uncomfortable. Defensive individuals often respond better when they see transparency and honesty upfront. The key isn't to be overly concerned with making the feedback sound positive, but rather to convey it in a way that demonstrates you’re invested in their growth. The more you try to package criticism softly, the more it dilutes the message, which can cause further defensiveness.

It's important to understand the physical environment first when delivering constructive feedback. First, the candidate should feel comfortable in the setting and the manager should start the conversation softly. Second, be specific with the feedback is crucial and not be ambiguous. Lastly, it's important to provide solutions after the feedback. This conversation should be collaborative, and the candidate should feel comfortable with giving their thoughts as well.

To offer constructive criticism to a defensive candidate: Start with positives to ease tension. Be specific about the issue, focusing on behaviors, not personal traits. Use a collaborative tone, showing you're there to help them improve. Encourage self-reflection by asking open-ended questions. Offer actionable solutions and support for improvement.

Providing feedback during an interview is something I value, though it's not common practice. I see it as an opportunity to assess if a candidate is open to feedback and willing to grow. Soft skills and communication are key in these situations—it's not just about what you say but how you say it. The most important thing is that feedback is given with the intent to help the person learn and improve. A candidate’s response to feedback is very telling. If they become defensive, it’s a red flag for me, as it suggests they may not be open to growth or collaboration.

I think you have to carefully approach a defensive candidate to ensure that feedback is received positively by first starting with stating that feedback is intendent to help the candidate improve and is not a criticism. It's important to be specific, to offer the opportunity for questions and to encourage the candidate to reach out and/or apply for future opportunities.
