Before you start
Failure questions are one kind of behavioral interview question. If you want the full list of related questions first, the common interview questions page gives the wider picture.
Why interviewers ask this
The consequence of a weak answer is simple: the interviewer learns nothing about how you behave when something goes wrong, so the question stops helping you. Indeed's career guide says an interviewer wants to know whether you can acknowledge your weaknesses and take responsibility for your failures. A related question, your greatest weakness, tests a similar quality from a different angle.
A weak answer denies any failure, picks a success in disguise, or explains why somebody else caused the problem. CNBC (Consumer News and Business Channel) Make It reports that career expert Mann says defensiveness or blaming others can raise red flags. A strong answer names a real mistake in plain words, shows the choice you made, and ends on a changed habit. This question is reported by candidates in many kinds of interviews.
A failure answer from first principles
- Failure question
- A failure question is a behavioral prompt, such as "tell me about a time you failed", that asks you to describe a real mistake or missed goal, so the interviewer can see how you take responsibility, what you changed afterwards, and whether you can talk about setbacks calmly.
- Contained failure
- A contained failure is a real mistake with a limited, recoverable cost, such as a missed data point or a late handoff, that you can describe in full without hiding its size or its cause, and from which you can name a specific change.
In plain words
Think of a pilot's debrief after a flight. The pilot does not pretend the flight was perfect, and does not spend an hour on the bumpy part. The debrief states what happened, who made which call, and what will be done differently next time. The analogy breaks in one place: an interview answer is spoken in about a minute, so you cannot cover everything a debrief would.
In one precise sentence, a failure answer is a short STAR story in which the Action is your own decision and the Result is what you learned or changed. The University of Cincinnati's career page says STAR stands for Situation, Task, Action, and Result. The full order is explained on the interview answer structure page.
Step 1: Choose a contained failure
Pick a real mistake where you were the main decision-maker and the damage was limited. CNBC Make It quotes the expert as saying a failure need not be catastrophic: it could also be considered a mistake, for example misreading a direction or missing a data point.
Input: your list of past work or study events. Output: one contained failure. Choose one where you can name what you did differently afterwards, because that is the part the answer is built around. Avoid a mistake that questions your honesty, and avoid a "failure" that is really a strength in disguise. You now have a story; the next step sets the scene without letting it grow.
Step 2: Set the scene briefly and own your part
Say the situation and your task in one or two sentences, then say what you did. The University of Cincinnati page advises that in the Action step you focus on your own contribution and use "I" rather than "we".
Input: the contained failure. Output: a plain statement of the mistake and your decision. State facts, not feelings, and do not explain why somebody else made it hard. Amazon's leadership principles page says its leaders never say "that's not my job", which is the attitude a failure answer should show; the Amazon Leadership Principles page covers the rest. A good test is whether a listener could say in one sentence what you personally got wrong.
Step 3: Give what you changed as much time as the action
The Result is the heart of a failure answer. CNBC Make It reports that its expert, Mann, calls the result the most important part: what you learned and how you changed your approach. Most important does not mean longest, so give it at least as many words as the action. The University of Cincinnati page adds that even when the outcome was not positive, you should focus on your strengths and resilience.
Input: the mistake and your decision. Output: a changed habit or a system, plus its effect if you can measure it. For example, after a data-analysis error, you might add a checking step before every report goes out. A measured effect makes it stronger; in the illustrative case here, late handoffs fell from three to zero in the next quarter. Amazon's Learn and Be Curious principle says leaders are never done learning and always seek to improve themselves, and this step is where you show it.
Step 4: Fit the answer into the time you have
A recruiting firm suggests aiming for 60 to 90 seconds, long enough to cover all four parts and short enough to hold attention. That is an opinion, not a standard, but it is a useful target for a spoken answer.
At an illustrative speaking rate of 150 words per minute, 75 seconds is about 188 words. An illustrative split of 20 percent for situation and task, 40 percent for action and 40 percent for result and lesson gives about 38, 75 and 75 words.1 The split is a planning heuristic, not a rule from a source. Its purpose is to stop the story from taking over. Cut the situation first, because the interviewer needs only enough context to follow the mistake.
Step-by-step description
- Pick a real, contained failure.
- Set the scene briefly and say I.
- Give it as much time as the action.
- Aim for about a minute.
- Choose a real, contained failure.
- Give what you changed as much time as the action.
Text description of the diagram
- At 75 seconds the answer is about 188 words.
- Situation and task get about 38 words; action and result each get about 75.
Knowing it is half the job. Saying it is the other half.

Start Free Trial →The Staff-level answer
Tell me about a time you failed.
On a reporting project I took a number from a spreadsheet without checking that the date range matched the rest of the report, and the summary I sent was wrong. I found out when a colleague asked about one figure. I told my manager the same day, sent a corrected version, and said which figure had been affected. Afterwards I added a short checklist, run before anything is sent, that compares date ranges and totals against the source. In the next quarter, the number of corrections I had to send dropped from three to zero. That checklist is now part of how I work.
What makes it Staff-level: the failure is named without excuses, the first action is to tell the people affected, and the ending is a system that outlasts the incident, not a promise to be more careful. The corrections figure is illustrative, not a measurement.
The rubric
| Dimension | Weak answer | Strong answer | Staff answer |
|---|---|---|---|
| Choice of failure | None, or a strength in disguise | A real, contained mistake | A real mistake where you were the decision-maker |
| Ownership | Blames people or tools | Says "I" and states the error | States the error and the first fix, before being asked |
| Result | Ends on the outcome | Names what you learned | Names a changed system and its effect |
| Communication | Long story, late point | Clear order, about a minute | Clear order, the lesson gets at least as many words as the action |
| Follow-up readiness | Surprised by "what else?" | Has a second example ready | Can say how the habit has held up since |
This table describes what a strong answer shows; it is advice, not a published scoring sheet from any employer.
Three variants of this question
What is your biggest failure? (with an example)
"What is your biggest failure?" is the same question with a larger frame. Use the same contained failure, but say why it was the one that taught you most. Do not reach for a dramatic story; a real, modest one told well beats a large one told defensively. An illustrative example: "I estimated a feature at two weeks without allowing for testing, and the launch slipped by a week. I told my manager as soon as I saw it and re-planned with the team. Since then I add a testing buffer to every estimate and have a colleague review it before I commit." The full example answer walks through a complete version.
How do you react to failure?
Reacting to failure well means acknowledging it, telling the people affected, fixing it, then changing the process. This version asks for a pattern, not one story, so answer in two sentences: your habit, then one short example to prove it.
Tell me about a project that did not go as planned
A project that did not go as planned is a failure that may be shared, so separate the part you controlled from the part you did not, and keep the focus on your decisions. Name what you would do differently today, not who else was at fault.
Common mistakes
- "I can't think of a time I failed." (wrong) The interviewer is checking for accountability, and Indeed says they want to see you acknowledge weaknesses. (right) "A mistake I made last year was ..."
- "It wasn't really my fault; the brief was unclear." (wrong) CNBC Make It's expert says blaming others can raise red flags. (right) "I should have asked to confirm the brief before starting."
- "My biggest failure is that I work too hard." (wrong) It disguises a strength as a weakness. (right) State a real error with a real cost.
- "The project failed, the end." (wrong) The answer stops before the part that matters. (right) "Afterwards I changed ... and the effect was ..."
- "We missed the deadline." (wrong) "We" hides your decision, and the Cincinnati page asks for "I". (right) "I underestimated the testing time."
Follow-up questions
Can I use a failure from school or a side project?
Yes, if it is real, you made the decision, and it cost you something. The interviewer wants to see accountability and a changed habit, and the setting matters less than that. Prefer a work example when you have a good one, and say plainly what was at stake.
What is a good example of a failure to use in an interview?
A good example is a contained one with a real cost, such as a missed data point, a late handoff or a misread direction. It should be a mistake where you made the decision and can name a change you made afterwards.
Should you say you have never failed?
No. It reads as evasive, and the question is designed to see accountability. If you struggle to find one, choose a small mistake you did not catch early.
How long should a failure answer be?
About a minute to a minute and a half is a sensible target, though that figure is a recruiting firm's opinion. Keep the situation to a sentence or two and let the result get at least as many words as the action. For the fully worked version of the most common phrasing, see tell me about a time you failed.
Which Amazon principles does a failure answer touch?
In our judgement, Ownership, Earn Trust and Learn and Be Curious map most directly. Earn Trust fits because Amazon's page says leaders are vocally self-critical, even when doing so is awkward or embarrassing, which is how an honest failure answer sounds. The Amazon leadership principles page covers the full list.
- Choose a real, contained failure, not a disguised strength and not a catastrophe.
- Use "I" and state your own decision plainly; do not blame others.
- Give the Result and the lesson at least as many words as the Action.
- A changed system, with its effect, is stronger than a promise to be more careful.
- Aim for roughly a minute, with the situation cut to the minimum.
