The Hidden Career Killer: Bad Communication Skills

You can be very good at your job and still be overlooked. Sometimes the problem isn't your capability, it's whether people can see it.

I learnt this the hard way.

👉 For 15 years I worked in business development roles. I had the qualifications, I was ambitious and I knew my industry.

But put me in a meeting - and I crumbled.

I struggled to get my words out. Presentations were uncomfortable. I would lose my train of thought, stutter over my sentences and spend so much energy worrying about how I was speaking, that I wasn't focused on what I was actually trying to say.

The frustrating part was that I knew I was capable of doing the job, but capability isn't always what other people experience.

They experience the discomfort in a meeting, hear the presentation, listen to the answer you give in an interview, and watch how you respond when someone challenges your idea - and this is what creates one of the most uncomfortable realities of professional life:

💡Your career can be affected by a skill that has very little to do with how good you are at your actual job - it’s your communication.

Being good at your job isn't always enough

👉 Most of us spend years building technical expertise.

• We study, earn qualifications, learn our industry, and we become better at what we do. However, somewhere along the way, the game changes:

• We get promoted and suddenly we’re expected to explain our thinking to a wider group of people.

• We apply for a new role and have to convince an interviewer that our experience translates to the position.

• We find ourselves presenting to executives who don't have the same technical background as us.

• We need to influence a client who doesn't care how much research we've done - they simply want to know what we recommend and why.

The further we progress, the more often our career depends on our ability to communicate what we know, rather than simply knowing it, and this can catch people by surprise.

I've seen highly experienced professionals who can solve incredibly complex problems struggle to explain the solution in a meeting.

I've seen people with impressive CVs give weak interview answers because they can't structure their experience into a compelling story.

And I've watched smart people with genuinely good ideas lose the room because they take too long to get to the point.

💡None of these people suddenly became less capable, it was their communication simply not allowing their capability to come through.

The problem isn't always confidence

We often describe this as a confidence problem.

👉 "Be more confident."

👉 "Speak with more authority."

👉 "Don't be nervous."

I've always felt this advice is not word salad.

When we're standing in front of an interviewer, a room of executives, or a senior client, telling ourselves to "be confident" doesn't give us anything practical to do.

A better place to start is understanding what happens to your communication when pressure arrives.

• Do you speak faster?

• Do you start filling every silence with "um", "so" or "you know"?

• Do your answers become longer because you're trying to prove that you know what you're talking about?

• Do you give the background before answering the actual question?

• Do you lose your structure halfway through?

These aren't character flaws - they're patterns, and patterns can be changed.

I had to learn this myself. Because of my stutter, I became hyper conscious of things that many speakers never think about: pace, rhythm, pauses, sentence construction and what happens to your thinking when you are speaking under pressure.

Over time, I realised something that changed the way I approached communication.

💡Speaking better is about understanding what you're doing when you speak, not becoming a different person.

When your brain gets ahead of your mouth

👉 One of the biggest challenges in interviews and high-pressure conversations is that people start speaking before they've worked out what they want to say.

You probably know the feeling.

Someone asks you a question - you immediately start answering.

Halfway through the first sentence - you're still working out your answer.

Then you remember another point, then another, and another - so you add that too.

Five minutes later, you've technically answered the question, but you've taken the listener on a journey they didn't ask for.

I've done this myself, and the solution isn't to think faster. In fact it's the opposite - slow down enough to think.

👉 That was the thinking behind my recent article, How to Think Fast by Speaking Slow.

When we're under pressure, we often assume that a faster response will make us appear more confident or capable. In reality, giving yourself a moment to pause can make your answer clearer, more deliberate and easier to follow.

That 3-second pause can feel enormous when you're the person speaking, however to the person listening, it usually feels like thoughtfulness.

This is particularly valuable in an interview.

Imagine being asked:

"Tell me about a time you had to deal with a difficult stakeholder."

You could immediately launch into the background, or you could pause, think about the story you want to tell and then give the interviewer a clear answer.

💡The second approach is about giving your thinking enough space to catch up with your mouth.

The more experienced you become, the easier it is to overcomplicate things

There's another communication trap that tends to appear as people progress in their careers.

👉 We start knowing too much. It might sound like a good problem to have, however it isn't always.

When we've spent ten years working in an industry, you understand the history, the technical details, the exceptions, the politics and all the reasons something works the way it does.

So when someone asks us a simple question, we give them ALL of it.

I've been guilty of this. And at some point, I know you have too.

We want the other person to understand the full picture, so we give them the full picture. However, great communication isn't about transferring everything you know.

It's about deciding what matters to this person - in this moment.

• A hiring manager doesn't need your entire career history, they need to understand why your experience makes you a strong fit for the role.

• Your manager doesn't necessarily need every detail behind your recommendation, they need to understand the recommendation, the reasoning and what you need from them.

• A client doesn't need to know everything you've researched, they need to understand what you recommend and why.

💡That is one of the biggest transformations that happens as you progress professionally - we move from demonstrating what we know to making what we know useful to someone else.

And that requires communication.

The details people notice without realising they're noticing

👉 Communication also gets reduced to the words we use.

Listen carefully to two people saying exactly the same sentence and you'll notice that the experience can be completely different.

• One person could race through it, and another pauses between ideas.

• One uses filler words after almost every sentence.

• Another leaves enough silence for the listener to process what they've said.

• One speaks in long, winding sentences.

• Another gets to the point and stops.

Do you relate to any of these?!

None of these things necessarily make someone a better or worse person, however they can change how the message comes across.

I became fascinated by this during my own journey with speaking. I spent years experimenting with pace, rhythm, distraction and sentence construction because I needed to find ways to communicate more effectively.

Eventually, those experiments became a much bigger lesson for me:

Communication is trainable.

You don't have to be naturally charismatic.

You don't have to be the loudest person in the room.

You don't need a naturally powerful voice.

💡You simply need to become more aware of what happens when you speak, particularly when the stakes are higher.

So what can you actually do about it?

👉 Start with the moments that matter most to your career.

If interviews are where you struggle, don't practice "communication" in the abstract. Practice answering interview questions.

• Record yourself.

• Listen back.

• Notice how long it takes you to actually answer the question.

• Notice where you start rambling.

• Notice how often you use filler words.

• Notice whether you give the point early or make the listener wait for it.

• Then try again.

If meetings are the problem, practice explaining your ideas in a much shorter format. Take something you know well and explain it in 60 seconds to someone who knows nothing about it.

If presentations are difficult, record the first two minutes. That's often where nerves are strongest and where your pace reveals the most.

If you find yourself speaking too quickly, don't simply tell yourself to "slow down". Practice deliberately putting pauses between ideas.

And if you struggle when someone asks an unexpected question, practice answering questions you haven't prepared for.

💡The goal isn't perfection, it's awareness, because we can't change a pattern we haven't noticed.

This is why I built SpeakerLab AI

👉 For much of my career, I worked on my speaking through repetition, experimentation and self-analysis.

Eventually I wanted something more measurable.

I wanted to know what was actually happening when I spoke - and that thinking became part of the foundation for SpeakerLab.

SpeakerLab gives you a way to practice communication in realistic situations and receive feedback on things such as pace, filler words, conciseness, storytelling and other aspects of your delivery.

The important part isn't the technology itself, it's what the technology allows you to do.

• You can practice before the interview.

• You can test an answer before the meeting.

• You can try telling the story again.

• You can see the patterns you might not notice when you're simply having a conversation.

💡The more you practice in low-pressure situations, the less unfamiliar those situations become when they actually matter.

Don't let an untrained skill become a career ceiling

👉 If you're good at what you do but feel that your communication isn't keeping pace with your career, don't automatically assume you have a confidence problem.

You may simply have a skill that hasn't been deliberately trained yet.

And that's good news, because skills can be trained!

We can:

• slow down

• learn to structure an answer

• become more concise

• practice thinking before we speak

• learn what happens to our delivery when we're under pressure, and

• get better at making our expertise understandable to the people who need to hear it.

💡Our career shouldn't be limited by something we haven't learnt to do well yet. Communication should be a part of our professional toolkit, so treat it that way.
