To answer "what are your weaknesses", name one real weakness that is not central to the job, explain what you are doing about it, and give a short piece of evidence that it is improving. Interviewers are testing self-awareness and honesty, not looking for a flaw to reject you on. Avoid disguised strengths like "I work too hard".

Why Interviewers Ask About Your Weaknesses

"What is your greatest weakness?" makes most candidates nervous, because it feels like a trap. It isn't one. Everyone has weaknesses, and the interviewer knows it. What they want to see is whether you know yours, whether you are honest about it, and whether you do something about it.

The question often comes straight after "what are your strengths?", or as a pair: "what are your strengths and weaknesses?". Preparing both together keeps your answers consistent.

What it tests

  • Self-awareness: can you see your own gaps clearly, without being defensive?
  • Honesty: will you give a real answer, or a rehearsed non-answer?
  • Growth: when you find a gap, do you work on it, and can you show progress?

A Simple Formula for Your Answer

1

Name one real weakness

Pick something true that you have actually noticed or been told in feedback. Say it plainly in one sentence. One weakness is enough; you do not need a list.

2

Show what you are doing about it

Describe the specific habit, tool or training you use to manage it. "I block an hour every Friday to plan the next week" is far stronger than "I am working on it".

3

Give evidence of progress

One short result: feedback that changed, a deadline you now hit, a presentation that went well. This turns the answer from a confession into a story of growth.

4

Keep it short and move on

Thirty to sixty seconds is enough. End on the progress, not the problem, and let the interviewer ask a follow-up if they want more.

Good Weaknesses to Mention in an Interview

The best weakness is a real one that is not essential to the job you are applying for. These are common, honest and easy to show progress on. Pick one that is true for you.

  • Public speaking or presenting: frame it with the practice you are doing, such as volunteering to present at team meetings.
  • Delegating: common in people moving into lead roles. Show how you now hand work over with clear briefs.
  • Saying yes to too much: show the prioritisation habit you use now, and how you push back politely.
  • Getting lost in detail: show how you set a "good enough" point and time-box polishing.
  • Impatience with slow processes: show how you learned to work within them, or improve them properly.
  • Limited experience with a tool or skill: name a skill that is useful but not core to the role, and the course or project you are using to learn it.
  • Giving direct feedback: show the structure you now use, and a conversation that went well.
  • Asking for help too late: show how you now flag blockers early, for example at a set point in each task.
  • Self-criticism: show how you now review work against agreed criteria rather than your own perfection.
  • Organisation and time estimates: show the planning system you use and how your estimates have improved.

A check before you choose: if the weakness is the main skill in the job description, pick another one. A data analyst should not lead with "I struggle with attention to detail".

Example Answers by Career Stage

Example: graduate or entry level
My weakness is presenting to groups. At university I avoided it, and in my first group project my part of the presentation was rushed. Since then I have joined a speaking society and volunteered to present our team updates in my internship. The first one was nervous, but by the end of the summer my manager said my updates were the clearest on the team. I still prepare more than most people, but I no longer avoid it.
Example: mid-career professional
I used to take on too much. I like helping, so I said yes to every request and some of my own deadlines slipped. My manager pointed it out in a review two years ago. Now I check every new request against my current priorities and, if it doesn’t fit, I say when I could do it or who else could help. I haven’t missed a project deadline since, and I’m more useful to people because I deliver what I promise.
Example: new manager or senior professional
Delegation. When I first led a team I kept the hardest work for myself because it was faster, and the team didn’t grow. I now write a short brief for every task I hand over, agree check-in points instead of watching over it, and accept that the first attempt might not be how I would do it. Two people on my team have since taken over areas I used to own, and I spend more of my time on planning, which is the job.
Example: "What are your strengths and weaknesses?"
My main strength is untangling messy problems: in my last role I rebuilt our reporting so the weekly numbers took one hour instead of a day. My weakness is that I can spend too long perfecting things. I now agree a "done" standard with my manager before I start, and I time-box the polishing. It has made me faster without hurting quality.

Mistakes to Avoid

Disguising a strength as a weakness

"I’m a perfectionist" or "I work too hard" with nothing behind it reads as evasive. Interviewers hear it constantly and usually mark it down.

Saying you have no weaknesses

It suggests low self-awareness or that you are hiding something. Always have one real answer ready.

Choosing a weakness that is core to the job

If the role is all about deadlines, "I struggle with deadlines" is a reason not to hire you. Check the job description first.

Over-sharing or self-criticising

This is not a confession. Name the weakness, show the fix and the progress, then stop. A long answer about a flaw leaves the flaw as the memory.

No action or evidence

A weakness without a plan sounds like a problem you have accepted. The action and the progress are what make the answer good.

Practise Your Answer Out Loud

This answer is easy to write and hard to say well. Under pressure, people either freeze or talk too long about the flaw. A few out-loud run-throughs fix both.

MockIF gives you that rehearsal. It builds a mock interview from your CV and the job description, asks the questions real interviewers ask, follows up when an answer stays vague, and gives you scored feedback on each answer, in voice or avatar mode. It is free to start with 5 credits, then monthly or 3-monthly plans, or one-off credit packs (see pricing). Try an AI mock interview to hear how your answer sounds.

For the evidence part of your answer, the STAR method keeps a short story clear.

Frequently Asked Questions

What is a good weakness to say in an interview?
A real weakness that is not central to the job, with a clear action you are taking and evidence of progress. Common good choices are public speaking, delegating, saying yes to too much, or a skill that is useful but not core to the role.
Should I say "I am a perfectionist"?
Only if it is genuinely true and you can describe its real cost and what you do about it, such as time-boxing work. Said on its own, it sounds like a strength in disguise and most interviewers see through it.
How many weaknesses should I give?
One, explained well. Have a second ready in case the interviewer asks "anything else?", but do not volunteer a list.
How do I answer "what are your strengths and weaknesses?"
Give one strength with a short example, then one weakness with what you are doing about it. Keep both to about 30 seconds each and end on the progress you have made.
Can I use a weakness I have already fixed?
Yes, if you are honest that it was a weakness and show how you fixed it. It works best if it still needs some attention, so it does not sound like you are avoiding the question.
What weaknesses should I avoid mentioning?
Anything core to the job, anything that raises concerns about honesty or reliability (such as lateness or missing deadlines without a fix), and personal matters unrelated to work.
