Interview Preparation for Experienced Professionals: Why Good Work Goes Unheard, and What Fixes It
A paramedic came to me a few months ago after missing out on a promotion. He had been in the service for years. He was calm under pressure, trusted by his colleagues and good at a job few people could manage for a single day. The new role was one band up, and for the first time it would mean managing people in his team. When we talked through his previous interview, the problem was clear within minutes. He had described his clinical work well, said very little about his strengths, and said almost nothing about leadership.
He had the ability. What the panel had not heard was any evidence that he was ready to lead, and a panel can only score what it hears. I have seen versions of this for fifteen years. The longer someone is good at a job, the harder it tends to become for them to explain why, and an interview asks them to do exactly that in a few minutes, to people who have never watched them work.
Why experience works against you in the interview room
Experience ought to be an advantage, and on paper it usually is. In the room, it can work against you because the things you do best are the things you have stopped noticing. Early in a career, each achievement feels visible because it is new and hard won. By mid-career, your strongest work has become routine, and routine is very difficult to describe with any precision because you no longer experience it as effort.
Long service adds a second layer. One thing I have noticed with professionals who have stayed in one organisation or one role for many years is that being relied upon gradually becomes the way they describe themselves. They talk about what they absorb, whether that is the difficult rota, the awkward stakeholder or the colleague who needs steadying, and say far less about the specific value they bring. Over time the two start to feel like the same thing, yet a panel can only award marks for the second.
The interview itself also changes as you progress. Early interviews largely test what you can do. At mid-career and beyond, they test how you think, including what you weighed up, what you decided and why. Experienced candidates often answer at the level of tasks when the panel is listening for decisions, which is exactly where my paramedic client had lost ground. His answers were full of what he had done and almost empty of the judgement that sat behind it.
When an interview goes badly, this is usually diagnosed as a confidence problem. I rarely find that it is. The experienced professionals I work with generally know they are good at their jobs, and telling them to believe in themselves adds very little. What they lack is evidence they can put into words, and confidence built on reassurance tends to fade at the first follow-up question. Confidence built on evidence you have gathered yourself lasts, because you know exactly what you did and what came of it.
Interview preparation for experienced professionals starts with strengths
Before you prepare a single answer, get clear on your strengths. By strengths I mean the things you do well that also give you energy, which is a narrower list than everything you are able to do. A skill is something you can do. A strength is something that fuels you as you do it. You can be excellent at producing detailed reports or managing a difficult stakeholder and still walk away from both exhausted every time.
The test I use with every client is simple. Does this thing you are calling a strength actually fuel you, or is it simply something you happen to be able to do? Self-assessment has limits here, because people tend to underrate whatever comes easily to them. A validated diagnostic gives you an outside reference point, which is why the StrengthscopeLeader profile sits at the start of Ascent, my programme for senior professionals, before any positioning work begins.
Once you know your real strengths, you need words for them that stand up to questioning. Ask a room of professionals to describe their strengths and you will hear phrases like "I am a strategic thinker" or "I am good with people." None of it is untrue, but none of it tells a panel anything. A strengths statement that works has three parts: how you naturally operate, the situation where that becomes valuable, and the result for other people.
Put "I am a strategic thinker" through those three parts, and it becomes something like "I can step back from the day-to-day, identify which two or three decisions matter most over the next six months, and help the people around me focus their effort there." That version holds when a panel member asks for an example, and the original collapses. It does not need to sound impressive. It needs to sound true, and it needs to sound like you.
Build an Evidence Bank of three core stories
The instinct before an interview is to collect likely questions and draft an answer for each one. It usually leaves people with a head full of half-remembered scripts and a moment of panic when a question arrives worded differently. A small number of strong stories that can flex to fit almost anything a panel asks will serve you far better, and I call this your Evidence Bank. Under pressure, memory does not retrieve things in neat order, so treat preparation as reconstruction rather than memory and write your stories down before you need them.
Start with three stories. The first is a genuinely difficult problem, one where the right answer was not obvious at the start. The second is a time you led through ambiguity, or worked with people who did not immediately see things your way. The third is the story you would rather avoid, such as a decision that did not land as you expected or a moment where you got it wrong before you got it right. That third story is often your strongest, because it shows judgement and self-awareness, and a senior panel is listening for how you handle difficulty as closely as for how you succeed.
For each story, record the situation, the challenge, what you actually did and the outcome. If that sounds like the STAR method, it is built on the same foundation, and STAR remains a sound way to organise an answer. Where it falls short for experienced candidates is that it captures events without explaining the person behind them. So add one more line to every story, naming the strength that was operating underneath. That line moves an answer from describing what happened to showing how you work at your best, and it is the part senior panels are most interested in.
With my paramedic client, this was where the real work happened. We did not invent anything. We went back through his experience and drew out his strengths and the times he had already taken the lead, so that a panel could see a manager as well as a skilled clinician. The leadership evidence had been in his working life all along, but it had never been written down.
Prepare the shape of each story
Once your stories are written, resist the urge to memorise them word for word. A memorised answer breaks when a question comes out differently from the one you rehearsed, because you reach for the script, it does not quite fit, and the answer turns stiff or starts to wander. Know the shape of each story and its key facts, and let the wording adjust to the question in front of you.
Three habits make the biggest difference in the room. The first is listening to the whole question. One of the biggest mistakes I see professionals make is offering a good example that answers a different question, because they heard the first few words, recognised a topic and reached for a prepared story. Wait until the panel member has finished, take a breath, and ask yourself what the question is really asking.
The second habit is putting yourself in the answer. Use "we" for the shared goal and the result, and "I" for your decisions and your actions. Panels score what you did, and "we sorted it out as a team" hides the judgement they are listening for. Experienced professionals are often uncomfortable claiming credit, particularly in public service, but a panel cannot award marks for work it cannot attribute to you.
The third habit is saying your answers out loud before the day, because an answer that feels clear in your head often wanders once spoken. Practise with someone who will be honest rather than kind, whether that is a trusted colleague or someone who prepares candidates for interview professionally. Recording yourself on your phone also helps, since it puts a wee bit of distance between you and your own delivery. Watch it once with the sound off, then listen once with your eyes closed, and you will notice things you cannot hear from the inside.
What interview panels miss in experienced candidates
The problem does not sit only with candidates. Organisations regularly say they want to promote from within, and the data suggests they find it hard. DDI's 2025 HR Insights Report, based on responses from 2,185 HR professionals and 10,796 leaders, found that on average only 49% of critical leadership roles could be filled immediately by internal candidates.
The report does not attribute that gap to interviews, and there are plenty of reasons a role cannot be filled from inside, from genuine skill gaps to thin development programmes. My own view is that one contributor receives less attention than it deserves, which is how readiness is judged. Where selection rests heavily on a single interview, panels are scoring what candidates can articulate on the day. That tends to favour people who talk about their work fluently, and it can disadvantage people who have spent years doing the work rather than describing it.
Organisations frequently overlook what this costs. When a strong internal candidate misses out because their evidence never reached the panel, the organisation loses more than one appointment. The person who missed out may stop applying, conclude that they cannot be seen where they are, and start looking elsewhere. Follow-up questions that press for specific examples, and assessment that draws on more than one conversation, give panels a far better chance of seeing what they already have. This is much of the work I do with organisations that want a clearer view of their own people.

There is also sector guidance for health, civil service, education and technical interviews. Get Interview Edge: The Preparation and Question Book for £10.
The evidence is already in your working life
It is worth asking yourself a harder question than whether you are ready for your next role. Ask whether anyone, including you, has ever seen your evidence laid out clearly. The professionals who make the strongest progress are seldom the ones with the most impressive careers on paper. They are the ones who took the time to look properly at what they already bring and then chose to say it plainly.
If you have an interview coming up, your experience is unlikely to be the issue. The work that remains is making that experience visible, first to yourself and then to the people deciding, and that work is entirely within your control.
