"Why did you leave your last job?" — how to answer

Three properties. An answer missing any one of them creates a problem.

Short. Twenty to forty seconds. Length signals discomfort, and discomfort invites the follow-up you were hoping to avoid.

True. Not necessarily complete — you are not obliged to narrate everything — but nothing said that is false. References get taken, sectors are small, and a story that does not match is worse than any reason for leaving.

Forward-looking. End on what you moved toward, not what you moved away from. This single edit converts most weak answers.

"I left because the team was reorganised and my role narrowed to reporting. I want to be closer to the commercial decisions, which is what this role does."

Twelve seconds. True, unresentful, and it lands on the future.

Find your row. The framing differs; the three properties do not.

The last row is the one that decides interviews. A candidate who says "you will have noticed three short stints; here is what was happening and here is what I changed" is in far better shape than one who explains each move individually while the interviewer silently counts.

• [ ] Under forty seconds
• [ ] Everything in it is true
• [ ] It ends on what I want, not on what was wrong
• [ ] I have not criticised a named person
• [ ] I have not criticised the employer as an organisation
• [ ] A reference from that employer would not contradict it
• [ ] It does not invite an obvious follow-up I cannot answer
• [ ] I could say it in the same words if my former manager were in the room
• [ ] I do not sound defensive when I say it out loud — check this on a recording, not in your head

The last two are the real tests. A resentful answer usually sounds fine written down and audibly different when spoken.

Restructure

"The department was restructured last year and two teams were merged. My role came out of it narrower — mostly reporting, where before I had the forecasting and pricing work as well. I stayed through the transition because I wanted to see it handed over properly, and then started looking for something that puts me back closer to the commercial side."

Factual, no grievance, explains the timing, ends on the target.

Dismissed

"I was let go after eight months. The role required a depth of regulatory experience I did not have, and I underestimated that at the hiring stage — as did they, to be fair. Since then I have completed the compliance certification and spent a year in a role where that was a smaller part of the job, which is where the experience actually came from. It was an uncomfortable lesson and a useful one."

Honest, unusually brief for the situation, takes real responsibility without excessive self-criticism, and demonstrates what changed. It also avoids the trap of blaming the employer for a hiring decision the candidate also participated in.

Three short tenures

"You will see three roles in four years, so let me address that directly. The first ended when the project was cancelled. The second I left after ten months because the scope I was hired for never materialised — that one I should have diligenced harder before accepting. The third was a contract with a fixed end date. What I have changed is how I test a role before accepting: I ask to speak to whoever held it before, and I ask what the first six months actually look like. What I am optimising for now is somewhere I can stay five years, which is why I am looking at this level rather than one above it."

Names the pattern first, takes responsibility for the one that was genuinely a misjudgement, and states what is different. The last sentence does more work than the rest combined.

All three examples are invented. The situations, timelines and details are not real.

"Why are you leaving your current role?" Same answer, present tense, weighted toward what you are moving toward since you have not left yet.

"What would make you stay?" A probe for whether you are negotiating rather than moving. Answer honestly and briefly; if the answer is "nothing realistic", say the decision is settled.

"Your manager — what would they say about why you left?" A truthfulness check. Your answer should be consistent with what a reference would say, which is exactly why the self-check includes that item.

"Why did you leave after only eight months?" Do not become defensive at the "only". Answer the same way you would answer the neutral version.

Asked on a structured scoring form. Common in public-sector and government-linked processes, where the assessor records the reason against a criterion. Brevity and clarity help; nuance does not travel well into a box.

Sectors are small, and the reference check is real. Your answer will frequently be verified by someone who knows someone. This is the strongest possible argument for an answer that is short and true, and against one that is shaded.

Notice periods are long enough to be part of the answer. If you are still employed, say your notice period when you give the reason — it saves a question and signals that you have thought about the transition rather than just the exit.

Avoid criticising a government or government-linked employer specifically. Not because criticism is forbidden, but because the network overlap is high and the professional cost is asymmetric.

Family and personal reasons are usually accepted without probing. "Personal circumstances that are now resolved" is a complete and respected answer here, and you are not obliged to expand on it.

Can I say I left because of the manager?

Not in those words. Say what changed about the work or what you need from the next role. "The reporting line changed and the scope narrowed" describes the same situation without a verdict on a person.

What if I was genuinely treated badly?

You may well be right. The interview is still not the place to establish it — you have thirty seconds and no evidence, and the interviewer has no way to verify anything. State what you moved toward and keep it brief.

Should I mention I was not the only one let go?

If it is relevant and factual, yes — "the function was cut from nine to four" is context, not an excuse.

What if I am still employed and they might find out I am looking?

Nothing in this answer requires disclosure to your current employer. If you are worried about discretion, say so; asking that the process be kept confidential is normal and reflects well on you.

What if the real reason is money?

Say it is part of it, and give the other part. Compensation alone as a reason tells them you may leave for the same reason again — and it is handled properly in the salary conversation, not here.

Write your answer, time it, record it. Forty seconds, true, ending on the future. If it is longer than that, something in it is doing defensive work.

Then: why do you want to work here, which is where the forward-looking half of this answer gets developed properly, and the interview question hub for the rest.

If the reason for leaving is genuinely difficult — a dismissal, a conflict, a pattern you cannot see your way around — that is worth rehearsing with someone before you say it to an employer. Mock interview coaching is built for it, or work through it in the self-paced interview preparation course.
