Quick takeaway: communication is the most self-reported competency in interviews and the hardest to assess without structure. To separate candidates who truly communicate well from those who speak with confidence, ask for situated evidence: a concrete case, the specific audience, what the candidate adjusted, and how they knew it worked. Strong answers describe process and outcome; empty answers describe style.
Every hiring manager who has brought someone on board based on the impression that “this person communicates really well” knows what happens three months later: messages do not land, conflicts are avoided rather than resolved, the team loses context. The problem was not verbal fluency. It was the absence of real communicative competence.
“Communication” is probably the competency most frequently listed on resumes and least rigorously assessed in interviews. Generic questions like “do you consider yourself a good communicator?” produce positive self-assessment and, at best, a well-told story. Assessing communication requires evidence of how the person behaved in real, specific, verifiable situations.1 Communicating well is a set of observable behaviors: message clarity, audience adaptation, active listening, feedback management.2 These behaviors show up (or fail to) in the accounts the candidate brings. For the full evidence-extraction method, how to run a structured interview covers the process end to end.
Why generic questions fail to assess communication
Most interviewers ask about communication and receive an answer about the person’s style, not their behavior. “I’m direct, I like to align well on things, I prefer open communication.” That describes a preference, not a competency.
Unstructured interviews reward candidates who speak well, not necessarily those who communicate well at work. Schmidt and Hunter’s (1998) synthesis, covering 85 years of research, shows predictive validity of .51 for structured interviews versus .38 for unstructured ones.3 For communication, the risk is higher: fluent candidates have a natural advantage in any interview. Situated questions and controlled probing are what levels that playing field.
Layer 1: ask for evidence of real, situated communication
Start with questions that require a concrete case. Without a case, there is no evidence.
”Tell me about a situation where you had to communicate something difficult or unpopular to your team or to a manager.”
Strong answer: describes the context (what was difficult, for whom), how they chose the moment and format, what they said exactly, and how the other person reacted. Mentions what worked and what they would adjust.
Red flag: answers in principle (“I always prefer transparency, I believe direct communication is essential”). No real case, no specific audience, no described reaction. Someone who has lived through a difficult conversation has the detail; someone who has not describes values instead.
”When was the last time a message of yours was misunderstood? What happened and what did you do?”
Strong answer: accepts that communication failures exist, describes what created the misinterpretation, how they noticed, and how they corrected it. The willingness to acknowledge a failure signals that the person has a feedback loop on their own communication.
Red flag: “I’ve never had a serious communication problem” or a generic example with no name, no context, no real consequence. Communication problems are universal; saying they never happen suggests either poor memory or poor self-awareness.
”Describe a project where you were responsible for keeping your team or other stakeholders informed. How did you do it?”
Strong answer: talks about cadence, the format chosen (written, verbal, meeting, message), how they decided what to include and what to leave out, and how they knew people had the right context.
Red flag: describes the intention (“I tried to keep everyone aligned”) without detailing what they actually did. Project communication has a process; someone who cannot describe the process did not have one.
Layer 2: probe for context, audience, and decision
The second and third questions about the same episode reveal what the first one does not.
”Who was the audience in that case? What specifically did you adjust for them?”
Strong answer: identifies the audience’s familiarity with the topic, what was simplified, what was emphasized, what was removed. Someone who adapts communication can describe the reasoning behind the adjustment.
Red flag: treats communication as a sent message. “I was clear and concise” with no reference to the audience’s level or what they needed to understand.
”How did you know the message landed? What told you the other person understood what you were trying to communicate?”
This question separates communication as a process from communication as transmission. Someone who communicates well has some verification mechanism, even if informal.
Strong answer: describes how they checked for understanding: a question back, a request for a paraphrase, an action that confirmed comprehension, a reaction that signaled something had not been clear.
Red flag: “I was clear, so the person should have understood.” Communication is not about what was sent; it is about what was received. The absence of verification is the absence of a feedback loop.
”Was there anyone in that situation who reacted differently from what you expected? What did you do?”
Strong answer: describes a real reaction (resistance, confusion, disagreement), how they noticed, and how they responded. Managing an unexpected reaction is where communicative competence actually shows.
Red flag: “everyone received it well” or a story where everything went smoothly. Communications that matter generate reactions. Absence of friction may mean absence of a real situation.
Layer 3: variation and difficulty — disagreement, technical to non-technical, written vs. oral
Use this layer when the role has specific communication demands or when earlier answers were thin. In leadership roles, communication and leadership intersect directly: the capacity to influence, deliver difficult feedback, and build commitment depends on effective communication, and the full evidence-capture process in how to run a structured interview shows how to document those moments as scored criteria rather than impressions.
”Tell me about a time you disagreed with someone more senior and had to communicate that disagreement.”
Strong answer: describes the context, how they chose when and how to raise the disagreement, what they said, and how the other person reacted. They do not need to have “won” — they need to have communicated constructively.1
Red flag: “I’ve never needed to disagree with a superior” (unlikely) or a story where they disagreed but say nothing about how they communicated it. The competency is in the how, not the outcome.
”Have you ever had to explain something highly technical to someone with no background in it? How did you handle it?”
For roles that bridge functions (tech and business, product and operations, finance and sales), this answer reveals whether the candidate can distinguish what the audience needs to know from what they themselves know.
Strong answer: describes how they gauged the audience’s level, the analogy or simplification choices made, and how they knew it worked. Sometimes mentions what did not work on the first try and what was adjusted.
Red flag: “I explained it simply and clearly” without detailing what was simplified or how comprehension was verified. Simplicity without process is assumption.
”Is there a difference between how you communicate in writing versus in person? Give me an example of each.”
Distinct channels, distinct demands. A candidate may be excellent in meetings and produce confusing emails, or the reverse. For roles that depend on both, evaluate both.
Strong answer: acknowledges the differences, describes how format and level of detail are adapted per channel, and brings distinct examples. Candidates who have communicated extensively in distributed (remote) environments tend to have sharper clarity around written communication.
Red flag: treats both channels as the same thing. Confuses oral confidence with written competence, or vice versa.
What it costs to hire someone with weak communication skills
Poor communication in roles that depend on alignment has a real cost: rework from lost context, unresolved conflicts, decisions made on incomplete information. That cost rarely shows up in the initial evaluation because the candidate seemed strong in the interview. The real cost of a bad hire puts those numbers in perspective.
One specific communication trap: accepting fluent answers as evidence of competence. Strong communicators tend to do well in interviews by the very nature of the skill. The risk is that articulate answers can be rehearsed, and verbal fluency in the interview does not predict how someone will deliver difficult feedback or keep a team informed under pressure. Situated probing is what separates competence from interview performance.
Frequently asked questions
Can communication be assessed in an interview?
Yes, provided you ask for situated evidence rather than self-assessment. Hargie (2017) defines competent communication as observable behaviors in a real situation: clarity, active listening, audience adaptation, and feedback management.1 Ask for concrete cases and evaluate those behaviors.
What is the difference between oral and written communication in the evaluation?
They are distinct channels with different demands. Oral communication requires live adaptation and context reading; written communication demands clarity without the support of tone and expression. For roles that depend on both, ask for specific cases in each channel. Do not assume that someone who speaks well also writes well.
How do I assess whether a candidate adapts their communication to the audience?
Ask for a case where they had to explain something technical to someone without domain knowledge. A strong answer describes how they gauged the audience’s level, what was adjusted, and how they knew it worked. A weak answer treats communication as a sent message, without checking whether it was received.
How do I tell a good communicator from someone who just speaks with confidence?
Confidence and clarity are not the same thing. Ask them to reconstruct a situation where they communicated something complex: someone who communicates well describes the format choice, the audience adaptation, and how they handled the reaction. Use the follow-up — “how did you know the message landed?” — to separate the two.
Does an introverted candidate communicate poorly?
No. Extraversion and communicative competence are distinct constructs. Morreale, Spitzberg, and Barge (2007) define communicative competence as a combination of motivation, knowledge, and skill observable in a real situation.2 Evaluate concrete behaviors, not social style.
Recrutador and communication assessment
Recrutador is a Hiring Intelligence Platform with five phases: the Strategist (chat-first consultant) defines the role’s evaluation criteria (Blueprint); the system generates a job description from those criteria; triages resumes with per-criterion coverage; the live HUD runs a semi-structured interview (every candidate starts from the same probe library, depth adapts per answer); and generates the Hiring Memo with cited evidence per criterion at the end.
For communication assessment specifically, the HUD follows answers in real time and suggests the next probing question based on what the candidate said — including the scenario variations that reveal whether communication is a competency or an interview performance. At the end, the Hiring Memo assembles the evidence by criterion.
Want to see it on your next hire? Talk to the team and we run your first interview with you.
