Most interview answers should take about one to two minutes. The University of Connecticut’s career centre puts the general figure at about two minutes, slightly longer or shorter depending on how complex the question is. For “Tell me about yourself”, North Dakota State University’s career advisers suggest one to two minutes, and Worcester Polytechnic Institute recommends preparing a two-minute response.
That rule of thumb is a good starting point, but much of the advice built around it is wrong or oversimplified. Below are six common myths about answer length, what the evidence from careers services and structured-interview guidance says instead, and a drill to get your timing right.
Target lengths by question type
These ranges are working guidance built from the careers-service figures above, not fixed rules. The panel’s cues always come first.
| Question type | Example | Target | Shape |
|---|---|---|---|
| Factual or yes/no | “Do you have a driving licence?” | A sentence or two | Answer, plus one useful detail |
| Opening question | “Tell me about yourself.” | 1 to 2 minutes | Present, past, why this role |
| Motivation | “Why do you want this job?” | About 1 minute | Two or three specific reasons |
| Behavioural | “Tell me about a time you…” | About 2 minutes | Brief situation, detailed actions, result |
| Technical or case | “How would you design…?” | Longer, in stages | Talk through your steps and check in |
| Strengths | “What energises you at work?” | Short and natural | Your genuine first response |
Myth 1: “Shorter is always safer”
Fact: in a structured interview, a very short answer can score poorly because it gives the panel too little to rate. The US Office of Personnel Management’s (OPM) guide to structured interviews describes rating each answer against example responses for each proficiency level, and says interviewers should take notes detailed enough to justify their ratings. It describes follow-up questions, called probes, as a way to help the candidate give the information needed to rate the response.
A 20-second answer does not look disciplined to a panel with a rating sheet. It leaves them to dig for evidence, and some panels have little time or permission to probe. Give enough detail that a note-taker could write down what you did and what happened.
Myth 2: “If they don’t interrupt, I should keep going”
Fact: silence is not encouragement. OPM’s guidance says interviewers must not challenge a candidate’s statements by word or expression, and structured panels are often busy writing. A neutral face and no interruption may simply mean the panel is following its process.
So you need your own stopping point. End on the result, then stop talking. If you are unsure whether you have said enough, ask: “Would you like more detail on any part of that?”
Myth 3: “Every answer should be a full STAR story”
Fact: the Situation, Task, Action, Result structure suits behavioural questions that ask for a past example. It is the wrong shape for a factual question and can be the wrong shape for strengths questions. The UK Civil Service, which uses strengths questions in its Success Profiles, says there are no right or wrong answers, advises candidates not to rehearse, and says interviewers are looking for your initial response. A two-minute STAR story in reply to “Do you prefer starting tasks or finishing them?” will sound scripted.
Myth 4: “More background makes the answer stronger”
Fact: background is where most long answers go wrong. The panel needs enough context to understand the problem; it does not need the organisation chart. A useful rule of thumb is to spend no more than about a fifth of a behavioural answer on the situation and task, most of it on what you did, and finish with the result.
Here is an illustrative before-and-after for “Tell me about a time you met a tight deadline”.
Illustrative long version, opening: “So, this was at my second job, which was a logistics company with about three hundred staff and four divisions, and I was in the planning team, which reported to operations, and at the time we were also changing our software, and my manager had just left, so…”
Illustrative tightened version: “Last March our largest client brought a shipment forward by a week, which left me three days to re-plan forty deliveries. I split the routes by priority, agreed overtime with two drivers, and sent the client a daily update so they could see progress. Every delivery arrived on time, and the client extended their contract that summer.”
The tightened version still has a situation, actions and a result, and it would take well under a minute to say. Add one more action or a detail about the result and it reaches the two-minute target with nothing wasted.
Myth 5: “Saying ‘we’ shows I’m a team player”
Fact: it makes your contribution hard to rate. OPM’s guidance tells interviewers to seek clarification when candidates say “we did…” or “our group…”. Every follow-up spent separating your role from the team’s is time you could have spent showing results. Use “I” for your actions and “we” for shared outcomes.
Myth 6: “In a timed video interview I should use all the time”
Fact: a time limit is a maximum, not a target. If a one-way video platform gives you three minutes, a complete two-minute answer that ends cleanly is better than a padded one. Before recording, use the preparation time to choose your example and your last sentence, so you know where you are going to stop.
In live video interviews it is harder to read the panel, so check in more often. A short pause after each main point gives the interviewer a chance to come in.
Signs you are running long
- You hear yourself say “anyway” or “so, basically” to get back on track.
- The interviewer stops writing and looks at the clock or the next question.
- You have not reached your own actions after about thirty seconds.
- You are adding a second example to an answer that only asked for one.
When it happens, finish with one sentence: “The result was…” and stop.
A 20-minute timing drill
- Pick five likely questions: the opener, a motivation question and three behavioural questions.
- Answer each one out loud while recording on your phone. Do not write a script.
- Play back and time each answer. Note where the situation ends and your actions begin.
- Cut background first, then repetition. Keep numbers, names of tools and results.
- Record again and compare. Most people find their second attempt is both shorter and clearer.
Your CV can help you here. Each bullet that already states an action and a result is a ready-made answer. If your bullets are vague, the resume builder prompts for measurable outcomes, the resume examples show how others phrase them, and resume questions answers common CV queries.
Frequently asked questions
How long should a ‘Tell me about yourself’ answer be?
About one to two minutes. North Dakota State University’s career advisers suggest one to two minutes, and Worcester Polytechnic Institute recommends preparing a two-minute response.
Is a five-minute answer ever acceptable?
For technical, case or presentation questions, yes, if you talk through your steps and check in with the interviewer. For standard questions, five minutes is usually too long.
What if the interviewer asks for more detail?
That is normal. Structured interviewers use follow-up probes to get the information they need to rate an answer. Give the detail directly without restarting the whole story.
Should I memorise answers to control their length?
Practise examples and key points, not full scripts. Memorised answers tend to sound recited, and the UK Civil Service specifically advises against rehearsing strengths answers.
