Communication skills
Four channels, fourteen skills, and the channel everyone forgets
Communication skill is the ability to move a message from your head into someone else’s with as little loss as possible — and the reverse. It splits into four channels, and most people are strong in two of them without knowing which.
The four channels
Communication is not one skill. Speaking well in a meeting and writing well in an email are different abilities that frequently do not coexist in the same person.
| Channel | What it covers | Where it is judged |
|---|---|---|
| Spoken | Clarity, structure, adapting to the audience, pacing. | Meetings, presentations, calls. |
| Listening | Active listening, questions, restating. | Everywhere — and it never shows on a CV. |
| Written | Structure, brevity, tone, asynchronous clarity. | Email, reports, team messages. |
| Non-verbal | Gaze, posture, distance, silence. | In person, on camera. |
The channel everyone forgets
The written one. Most lists of communication skills were written before half of all work became asynchronous. Today, someone who speaks superbly but sends an ambiguous email to fifteen recipients costs their team more than they gain in the meeting — because the email is read fifteen times and nobody can ask for clarification without cost.
The skills, one by one
Written as behaviours, so you can tell whether they are present.
| Skill | Channel | How you can tell it is there |
|---|---|---|
| Clarity | Spoken / Written | Nobody asks you to say it again. |
| Structure | Spoken / Written | You put the ask first and the evidence after. |
| Brevity | Written | Your email fits on one screen. |
| Adapting to audience | All | You explain the same thing differently to an engineer and a client. |
| Active listening | Listening | You say the meaning back before answering. |
| Questioning | Listening | You ask open questions before assuming. |
| Feedback | Spoken | You describe behaviour, not character. |
| Handling a difficult conversation | Spoken | You stay on topic as the temperature rises. |
| Presenting | Spoken / Non-verbal | The audience remembers one thing the next day. |
| Narrative | Spoken / Written | You give context before data. |
| Asynchronous clarity | Written | Your message does not require a second message. |
| Tone in writing | Written | You are not misread when your voice is missing. |
| Reading the room | Non-verbal | You know when to stop. |
| Using silence | Non-verbal | You leave a gap instead of filling it. |
How they are assessed in interviews
Nobody asks "do you have communication skills?" and expects to learn anything from the answer. They are assessed three ways, and two of them do not look like a question:
From how you answer, not what you answer
If your answer to a question runs four minutes and the interviewer loses the thread in the second, you have just answered the question about your communication skills — negatively. The structure of the answer is the assessment.
With a behavioural question
"Tell me about a time you had to explain something technical to someone outside the field." They want the situation, what you specifically did, and what happened. "I am good at simplifying things" is not an answer.
From the written trail
The email you used to confirm the interview counts. It is the only sample of your written communication they have before hiring you, and they read it.
What to write on a CV
"Excellent communication skills" appears on so many CVs that its information value is exactly zero. Worse: anyone who actually has them does not need to claim it, because it shows in how the CV itself is written.
| Instead of | Write |
|---|---|
| Excellent communication skills | Presented quarterly results to an audience of 40, every quarter for two years. |
| Team player with good communication | Coordinated communication between three departments to deliver X. |
| Strong written skills | Wrote the user documentation that cut support requests by 30%. |
The rule: a skill on a CV is worth something only when it comes with the circumstance in which it was exercised and a consequence that can be checked.
How they are developed
Two things separate people who improve from people who attend seminars and stay the same.
First: they pick a channel. You do not improve "your communication". You improve your writing, or your listening, or your presenting, one at a time, for four to six weeks. The channels transfer to each other very little.
Second: they get feedback on a moment, not on the whole. "How did I do?" returns politeness. "At the point where I explained the process — what did you lose?" returns information.
If you want one indicator for whether your spoken communication is improving: how many times you were asked for clarification in a week. It is the one number you cannot flatter, and it falls before you start feeling more confident.
Frequently asked questions
What are communication skills?
Fourteen of them, across four channels: spoken (clarity, structure, adapting, feedback, difficult conversations, presenting, narrative), listening (active listening, questioning), written (brevity, asynchronous clarity, tone) and non-verbal (reading the room, using silence).
Which one matters most?
Active listening, for two reasons: it is the only one that improves all four channels at once, and it is the one most often missing without the person realising — from the inside, listening in order to reply feels like paying attention.
How do I write them on a CV?
Never as an attribute. As a circumstance with a consequence: where you exercised the skill, with how many people, to what effect. The phrase "excellent communication skills" appears on so many CVs that it is no longer read at all.
Can a seminar improve them?
A seminar gives vocabulary and awareness, which are necessary but not sufficient. The skill changes when it is practised in real situations with feedback within a few days. The sign the seminar did not take: you can explain the skill better, but you cannot name a moment last week when you did something differently.
