What is your biggest regret? How to answer without oversharing
Choose a professional regret that is real but not damaging, such as not speaking up sooner, not asking for help, or staying too long in a comfortable role. Explain it in a sentence or two, say what it taught you, and spend most of the answer on what you do differently now. Keep family, health, relationships and anything unethical out of it.
Why they ask
"What is your biggest regret?" is less common than "Tell me about a mistake," but it comes up, especially in senior roles and in more conversational interviews. The interviewer wants to see:
- Self-awareness. Can you look back honestly?
- Growth. Did it change how you act?
- Judgment. Do you know what's appropriate to share in an interview?
That last point is where people go wrong. "Biggest regret" sounds personal, so some candidates talk about a divorce, a parent's illness or a lost friendship. Those are real regrets, but an interview isn't the place, and it puts the interviewer in an awkward position.
What makes a good regret to share
| Good choice | Why it works |
|---|---|
| Not speaking up sooner about a problem | Shows you now raise issues early |
| Not asking for help when stuck | Shows you now ask well and early |
| Staying too long in a role where you weren't learning | Explains a move, and shows ambition |
| Not taking a stretch opportunity | Shows you now say yes to challenges |
| Not keeping in touch with mentors or colleagues | Shows you value relationships now |
| Not finishing a qualification sooner | Shows you followed through later |
| Keep it out | Why |
|---|---|
| Family, relationships, health, grief | Too personal, and hard to link to work |
| Anything illegal or dishonest | A red flag, whatever you learned |
| Regretting a past employer or job choice with blame | Sounds bitter |
| "I have no regrets" | Sounds unreflective or evasive |
| A disguised boast ("I regret working too hard") | Interviewers see through it |
A structure for your answer
- The regret, briefly. One or two sentences. No long backstory.
- Why it matters. What it cost: an opportunity, time, a result.
- What you learned. One clear lesson.
- What you do now. A specific habit, plus one recent example of it.
Steps 3 and 4 should take about two-thirds of your answer. The regret is only the setup.
Example answers
These are examples with made-up details. Pick something true from your own experience.
Example answer: not speaking up
"In my first job, I noticed our client reports had a calculation error, but I assumed someone more senior had already seen it. I didn't say anything for two months, and the client found it. I regret that, because I could have saved the team a difficult conversation. Since then, I raise things early, even if I'm not sure. Last quarter I flagged a pricing mismatch in my first week at a new team. It turned out to be real, and we fixed it before it went out."
Example answer: staying too long
"I stayed in my previous role about two years longer than I should have. It was comfortable and I liked the team, but I'd stopped learning. When I finally moved, I realised how much I'd held back. Now I check in with myself every year about what I'm learning, and I talk to my manager about stretch work before I get bored. It's partly why I'm interested in this role: it's a clear step up."
Example answer: not asking for help
"During my final-year project I struggled alone with the data analysis for weeks before asking my supervisor. She sorted it out in an hour. I regret the time I lost. Now I give myself a set time to work something out, and if I'm still stuck, I ask with a clear question. In my internship that meant I finished my first project a week early."
Example answer: a missed opportunity
"I was offered the chance to present our team's results at a company meeting and turned it down because I was nervous. Someone else presented my work. I regret that, because it was a good chance to be seen. Since then I've said yes to every presentation I'm offered, and I practise them out loud beforehand. I've given four this year."
Mistakes to avoid
| Mistake | Why it hurts | Try instead |
|---|---|---|
| Oversharing personal pain | Makes the interview awkward | Choose a work or study regret |
| A long story about the regret | Keeps the focus on the negative | One or two sentences, then the lesson |
| No "what I do now" | Suggests you haven't changed | End with a habit and a recent example |
| Blaming others | Sounds like you avoid responsibility | Own your part |
| A regret that's really a strength | Sounds rehearsed | Pick something genuine but recoverable |
Practice it out loud
Regrets can make your voice drop and your pace slow, which can make the answer sound heavier than you mean it. Practice so the regret is quick and calm, and the "what I do now" part sounds energetic. The interview answer review shows your pace across the answer. Speaking Coach can then ask the follow-up "What do you do differently now?" based on what you said.
Questions people ask
Can I say I have no regrets?
It's risky. It can sound like you avoid reflecting or are hiding something. Choose a small professional regret instead.
Is a personal regret ever okay?
Only if it's mild and clearly linked to work, like not learning a language that would help your career. Avoid family, health and relationships.
How is this different from "Tell me about a mistake"?
A mistake is usually one event. A regret can be a choice or a missed opportunity over time. Both need a lesson and a change. See tell me about a time you made a mistake.
Should my regret be recent?
Not necessarily. An older regret works well if you can show how long you've been acting on the lesson.
How long should my answer be?
About 45 to 60 seconds, with most of it on what you learned and what you do now.
