How to answer "Tell me about a time you made a mistake"

This question asks you to admit a mistake to someone deciding whether to hire you. Say what you got wrong in one plain sentence, near the start. Then spend most of the answer on how you fixed it and what you do differently now.

Amazon's guide to its interviews lists "Describe a time when you took a risk, made a mistake, or failed. What happened, and what did you learn from it?" among its sample questions. It says all candidates are evaluated "through the lens of" its Leadership Principles. One of them, Earn Trust, says leaders "are vocally self-critical, even when doing so is awkward or embarrassing." An answer to this question is your chance to show you can do that.

The structure: the mistake, how you found out, the fix, what you changed

Give the setting a sentence. Then say the mistake in one plain sentence: what you did or didn't do. Say how you found out, whether you caught it yourself or someone told you. Spend most of the answer on the fix: who you told, what you did first and how you put it right. End on what you changed so it won't happen again. If you can, add how that change has held up since.

Aim for about a minute, and no more than 90 seconds. It's a version of the STAR method that ends on what you changed. Write each part as a few words, then answer out loud from those notes.

The short answer

If they want it quick, two sentences will do: "I [the mistake], and I found out when [how]. I [the fix], and now I [what you changed]." Then stop and let them ask for more.

How to pick the mistake

Pick one that was yours: a step you skipped, a number you got wrong or a promise you couldn't keep.
Pick one with a cost you can name, like a wrong price, a confused customer or a shift left short.
Pick one that didn't hurt anyone or break a law.
Pick one you helped fix, so most of the answer is about what you did.
Pick one that left you with a step you still use. That's how the answer ends.
Pick one from the last few years. If you're a student or a new grad, school counts.

Six sample answers

The people and companies below are made up. Read each answer out loud with a timer. Each runs under a minute. Then swap in your own story and keep the shape.

At work

"Last year I put together our team's monthly sales report, which goes to every regional manager. One month I pasted in the wrong week's numbers for our biggest store, so it looked like their sales had dropped by a fifth. A regional manager emailed me that morning to ask what had happened there. I checked the file and saw the mistake was mine. Within the hour I sent a corrected report to the whole list, with one line at the top saying what I'd gotten wrong. Then I called the manager who'd asked, to make sure nobody had acted on the old numbers. Since then I check each store's total against our sales system before I send. It takes ten minutes, and I've sent eleven reports since without an error."

In customer service

"I answered calls for an internet and TV provider. A customer called to drop her TV package, and I told her the change would show on her next bill. That was my mistake. Her billing date had already passed, so the change wouldn't start until the cycle after. She called back three weeks later, upset about a bill that still had the package on it. I told her right away that I'd given her the wrong date. My supervisor approved a credit for that month, and I called her the next day to confirm it had gone through. After that I started reading the billing date off the account before I promised any date. I also asked to add that step to our cancellation checklist, and the team uses it now."

In retail

"At my last store job, I set up the signs for a weekend sale. I marked a rack of winter coats 40 percent off when the sale was 30 percent. On Saturday morning the registers rang them up at 30, and customers held up my signs. I told my manager right away that the signs were my mistake. She decided we'd honor 40 percent for anyone who'd picked a coat from that rack, and I swapped in the right signs within ten minutes. Six coats sold at the extra discount, about $90 in all. Then I suggested a step for every sale: two of us check each sign against the price list before the doors open. We kept doing it, and the signs matched for the rest of my time there."

A nurse

"On a night shift on my medical-surgical unit, I gave a patient pain medicine at 2 a.m. and didn't chart it until the end of my shift. At handoff, the day nurse saw no pain medicine charted overnight and was about to give a dose. I stopped her, told her I'd given it at 2 and charted it right then as a late entry. The second dose never reached the patient. It would have been a double dose. I told my charge nurse and filed an incident report, which is what our unit asks for near misses. Since then I chart each medicine at the bedside before I leave the room, and I haven't charted one late since."

A new manager

"In my first year as an assistant manager at a restaurant, I approved two vacation requests for the same Saturday in December without checking the schedule. That left our closing shift with one server instead of three. I found out on Wednesday, when one of the servers asked who else was closing. I didn't take back either vacation, since I'd already said yes. I picked up the closing shift myself and offered the extra hours to our part-timers, and one of them took it. Then I told the general manager what had happened before she heard it from someone else. Since then I approve time off only with the schedule open in front of me, and I haven't left a shift short that way since."

A college student

"As events chair of my college's marketing club, I sent the invite for our spring speaker night with the wrong date. It said Thursday the 14th, and the 14th was a Wednesday. I'd copied the line from the year before and changed only the number. Within a day, half the replies asked which night it was. That evening I sent a correction to the whole list with the right date, Thursday the 15th, in the subject line. I also emailed the speaker to make sure she still had the Thursday. Then I asked our president to read every invite before it went out, and I started checking each date against a calendar. I sent nine more invites that year, and every date was right."

What to leave out

A mistake that's really a strength, like "I work too hard." It sounds like a way around the question.
Blame. If other people played a part, say yours.
Words that hide who did it, like "Mistakes were made" or "The email went out." Say "I sent it."
A mistake that hurt someone or broke a law.
Names and private details: customers, coworkers, patients and numbers your company keeps private.
A long setup. Give the setting a sentence, then say the mistake.
Softeners, like "It was kind of a small thing" or "I guess I could have checked." Say it plainly.
An ending that stops at the apology. Finish on what you changed.

How to say the mistake out loud

The hardest sentence in this answer is the one where you say what you got wrong. Say it early and once, then move on to the fix.

Use "I" and a plain verb, like "I sent it with the wrong date" or "I told her the wrong day."
Let your voice come down at the end of that sentence. If it rises, the mistake can sound like a question. See how to stop upspeak.
Skip the nervous laugh and the extra apologies. Say it once, plainly, and go on.
Pause for a beat after it, then say what you did. If you tend to rush, see how to talk slower.

In a nursing or healthcare interview

If they ask about a mistake in patient care, pick one that didn't harm the patient, like one caught before it reached them or one in charting or a handoff. Say who you told and how you reported it, the way your unit asks: your charge nurse, an incident report or both. Then say what you changed, like a check you added or a step your unit now uses. Keep every patient detail out.

If you're a student or a new grad

Use school, a club, a team, volunteering or a part-time job. A wrong date on an invite, a step you skipped in a lab or a shift you mixed up all work. Keep the same four parts, and end on what you do differently now.

Practice it out loud

A chatbot can tidy up the words. You still have to say "That was my mistake" to a stranger without flinching, and you can't tell how that sounds until you hear yourself. So practice the way you'll give it: out loud and on a timer.

Write the four parts: the mistake, how you found out, the fix and what you changed. A few words each.
Answer from your notes into your phone's voice recorder, and time it.
Play it back. Check that the mistake took one sentence and the fix took most of the time.
Listen to the sentence where you name the mistake. If your voice went up at the end or you laughed, say it again until it comes out steady.
The next day, answer without the notes. Then have a friend ask the usual follow-ups: "How did your manager react?" and "What would you do differently?"

For the rest of the interview, there's a 15-minute routine in how to practice for an interview by yourself. The other common questions are in how to answer interview questions.

The same question in other words

"Describe a time you made a mistake", "Tell me about a mistake you made and how you handled it", "Tell me about a time you made a mistake at work and how you fixed it", "Tell me about a time you made a mistake and learned from it" and "Give me an example of a time you did something wrong" all ask the same thing. Answer them the same way: the mistake, how you found out, the fix, what you changed.

Practice it with an AI coach in Charisma Lab

Charisma Lab is a speaking coach on your iPhone. In Speak, tap INTERVIEW under PRACTICING FOR, then tap the center, say what the job is and tell the coach you're practicing "Tell me about a time you made a mistake." Tell your story one part at a time, since a pause of about two seconds ends a take. You hear each take played back. When something is off, the coach says what to fix, then the mic opens again.

To say the mistake so it sounds settled, try The Declarative in Train. It's open from the start in the Conviction track. It hands you a line like "I stand by my recommendation." and listens to how your voice ends. A take passes when you say at least half the line and its key word, and your last word comes out more than 5% lower in pitch than your average on the words before it. Setup is free. If you tap MAYBE LATER when it shows the price, then SKIP FOR NOW when it asks you to sign in, setup goes on to a short live session with the coach. After setup, the app needs Pro, which is $14.99 a month in the US. See pricing.

FAQ

How long should my answer be?

About a minute, and no more than 90 seconds. Give the mistake a sentence or two, and spend the rest on the fix and what you changed.

How big a mistake should I pick?

Big enough that it cost something you can name, like money, a deadline or a customer's patience. Small enough that nobody was hurt and you could put it right.

What if someone else caught it?

That's fine. Say who noticed in a few words, then spend the answer on what you did once you knew.

What if I can't think of one?

Think of a number you got wrong, a step you skipped, a date you mixed up or a promise you couldn't keep. Saying you've never made a mistake sounds like you won't admit one.

Should I say "I made a mistake"?

Yes, once, in plain words: "That was my mistake" or "I sent it with the wrong date." Then go straight to what you did about it.

Is it the same as "Tell me about a time you failed"?

They're close. A failure is usually a goal you missed. A mistake is one thing you got wrong, and most of the story is how you fixed it. One story can answer both if it fits. See how to answer "Tell me about a time you failed".
