Talking about your work without lying or shrinking

Six stories, prepared once

Most behavioural questions are variations on six situations. Write these out, once, properly, and you are ready for almost any version of them.

1. Something you built. The one you are proudest of, with who used it.
2. Something that broke, and what you did in the following hour.
3. A disagreement with a colleague or a manager, and how it resolved.
4. A time you were wrong about data: you reported a number and it was incorrect.
5. A time you pushed back or said no.
6. Something you had to learn quickly under real pressure.

Numbers 2 and 4 are the ones that decide rounds, and the ones almost nobody prepares.

The shape, without the acronym

One sentence of situation. What you did, specifically. The number. What you would do differently. Two minutes, not eight.

“The weekly revenue report was wrong for two months and I did not catch it. I had joined orders to order items to filter by category and then summed the order total, which counted each order once per item: revenue was inflated by about forty per cent. Finance found it, not me, which was the embarrassing part. I fixed it, republished the corrected figures with a note explaining the cause, and added a row-count check before and after every join in that pipeline. I now check counts on every join, and I would have caught it in week one if I had reconciled against the finance export at the start.”

That is under ninety seconds and it does five things: names a real error, quantifies it, admits how it was found, describes the systemic fix, and states the habit that came out of it.

Why the failure story matters most

They are hiring somebody who will one day break production. Everyone does. What they are buying is your behaviour in the hour afterwards: whether you notice, whether you say so immediately, whether you fix the cause or the symptom.

The failing answer is the deflection: “my weakness is that I care too much” or “I once worked too hard on a project”. Interviewers hear these several times a week and score them as an unwillingness to be examined, which is exactly the trait that makes an incident worse.

The other failing answer is a failure that was somebody else’s fault. If the story ends with a colleague being wrong, it is not a failure story.

“I” and “we”, precisely

Say “I” for what you did and “we” for what the team did, and be exact about the boundary. Interviewers cross-check by asking follow-ups (”how did you decide on the median?”, ”who wrote the retry logic?”), and an inflated claim collapses in one question. A candidate who says “the pipeline was mostly my colleague’s; I built the validation layer on top of it” gains credibility, not loses it.

Interviewing in a second language

If you are interviewing in English for a nearshore, remote or overseas role, the bar is being understood, not sounding native. Nobody is scoring your accent; they are scoring whether a colleague could work with you across a video call.

Four things that measurably help:

• Slow down by about twenty per cent. Almost all comprehension problems on calls are speed, not vocabulary.
• Short sentences. One idea each. Long clauses are where second-language speech becomes hard to follow.
• Ask them to repeat rather than guessing. “Sorry, could you say that again?” is normal and costs nothing. Answering the wrong question costs the round.
• Rehearse the six stories out loud until the words are automatic. This is the mechanism that matters: composing an answer and translating it at the same time consumes all your working memory, and there is none left for thinking. Rehearsal removes the composing half, so the whole load goes to the content.

Rehearse aloud, not in your head: silent rehearsal does not produce the automaticity.

Have the numbers ready

“About thirty users.” “Four hours down to fifteen minutes.” “Forty test cases, thirty-three correct.” “Three months, alone, alongside my job.”

Specific numbers read as memory. Vagueness reads as invention, whether or not it is, because a person who did the work remembers its size.

Free practice

Record yourself on a phone answering the six questions, and watch it back once. It is unpleasant and it is the fastest correction available: you will hear the filler, the length, and the place where you stopped answering the question. Then swap mock interviews with a peer. Paid coaching does the same thing with a bill attached.

The limitation

Some interviewers grade for “fit” in ways that are about them rather than you: accent, background, school, confidence performed in a particular cultural register. You cannot fix that from inside the room, and trying to will make you worse. Treat one bad room as data about the room, and pay attention only when the same specific feedback appears three times.
