Every hiring manager has met the candidate who says all the right things. Asked about a weakness, they offer something safe and pre-packaged: "I'm too much of a perfectin ist" or "I care too much about the team." It sounds like self-awareness. It is usually spin.

Genuine self-awareness is one of the four traits that sit under what's often called the 'soundness' coordinate of a career compass, alongside integrity, resilience and positive energy. Soundness is about whether someone has done the harder work of actually knowing themselves, not just knowing how to sound reflective. For management roles, this matters enormously. A leader who cannot see their own blind spots will struggle to manage a team, take feedback, or course-correct when something goes wrong.

Why this is hard to spot in a normal interview

Senior candidates have usually done a lot of interviews. They know the questions coming and they know the answers that land well. That is not dishonesty, it is preparation. But it means a standard question like "what's your biggest weakness" almost never surfaces anything useful anymore.

The goal is not to catch someone out. It is to get past the rehearsed answer to something specific and real. That takes better questions and, just as importantly, someone experienced enough to notice the difference between a considered answer and a polished one.

Questions that test for the real thing

Instead of asking candidates to name a weakness in the abstract, ask them to walk you through a specific moment where that weakness actually cost them something. Some prompts that work well in management interviews:

  • "Tell me about a decision you made in the last year that you'd make differently now. What did you miss at the time?"
  • "Describe a piece of feedback from a manager or a direct report that stung. What did you do with it afterwards?"
  • "Who on your last team found you difficult to work with, and why do you think that was?"
  • "What's something your team would say you're still not great at, even now?"
  • "Tell me about a time you were wrong in a disagreement with a colleague. How did you find out, and what happened next?"

Listen less for the answer and more for the texture around it. A candidate with real self-awareness will give you specifics: names of projects, what the actual mistake was, how they found out, what changed afterwards. Someone who is spinning will stay general, will pivot quickly to the lesson learned without dwelling on the discomfort, or will frame every past mistake as something that was really someone else's fault.

The follow-up question matters more than the first one

Anyone can prepare a good opening answer. Fewer people can sustain it under a second or third question. Ask "what did your manager say when you told them?" or "how did your team react?" A candidate who is being genuine will have an answer. A candidate who rehearsed a story will often stumble, because the follow-up wasn't part of the script.

How we build this into the process

This is exactly why The Appointment Firm insists on partner-led interviews rather than handing a shortlist over based on a CV screen. When one of our partners meets a candidate in person, we are not just checking competence against the job spec. We are probing for soundness: does this person actually know their own edges, or have they just learned to talk about them well.

We take the same approach into reference checks. A good reference conversation is not a box-ticking exercise. It is a chance to ask the same kind of specific questions we asked the candidate, and see whether the two stories line up. If a candidate told us about a mistake and a former manager tells a different version entirely, that is worth knowing before an offer goes out, not after.

For South African employers making a senior appointment, this kind of scrutiny protects both sides. It stops a business from hiring someone who looks strong on paper but folds under real pressure. And it gives good candidates, the ones who can actually talk honestly about their own gaps, a fair chance to stand out from the polished competition.

Get the right questions asked, by the right person

If you're filling a management role and want a shortlist that has already been tested for soundness, not just skill, we'd welcome a conversation. Get in touch with The Appointment Firm and let's talk about the role you're trying to fill.
