Why interviewers ask this

When an interviewer says tell me about a time you influenced someone without authority, the answer that arrives is nearly always a persuasion story with a clean ending. The candidate built a case, presented it well, and the other person came round. What that leaves out is the price, and there is always a price, because people with their own priorities do not abandon them because your slides were good. They trade. Something you wanted got smaller, or something they wanted got added to the deal, or you quietly agreed to carry a piece of work that was properly theirs and is still on your team a year later. Interviewers ask this because the version without a trade in it has usually been simplified until the interesting part fell out.

An answer that sounds fine

Our data team owned a pipeline my team depended on and it was breaking about once a fortnight, which meant our reporting was unreliable and we were losing credibility with the business. I had no authority over that team and no line into their planning at all. So I put together a short summary of every failure over three months, what each one had cost us in hours and in delayed reports, and I took it to their lead rather than escalating over her head. I framed the whole thing as a shared problem we both had an interest in solving instead of as a complaint about her team. She agreed to prioritise the fix in the following sprint, they rewrote the fragile part, and failures dropped to roughly one a quarter.

Where it breaks

Read it for what the other lead got out of the arrangement, and the answer is nothing. She had a backlog of her own, presumably with things on it she cared about and had promised to somebody, and the story asks us to believe she reprioritised because a colleague from a different team showed her a spreadsheet. That happens occasionally and it is not what happened here, or if it is, the candidate has left out why she was willing. There is a second absence. The story ends at the decision, in the sprint where the fix was agreed, and says nothing about the following quarter when the same pressure that made the pipeline fragile in the first place came back around. Somebody describing a time they persuaded someone should be able to say what the persuasion cost them, and this account is priced at zero.

The follow-up

What did they want instead, and what did you give up?

She wanted us off her backlog, honestly, more than she wanted the fix. Part of the deal was that my team took over the reporting layer that sat on top of the pipeline, which had been hers, and that was about a day a week of my analyst's time from then on. I did not present it that way internally. I presented it as us getting control of our own reporting, which was true and was also not the reason it happened.

There is the trade, and taken on its own it is a completely reasonable one. He bought reliability with a day a week of somebody's capacity, permanently, and the person who paid it was an analyst on his team rather than him. What is more revealing is the last sentence. He described the outcome internally in the language of autonomy rather than as a cost he had accepted, which means his own team believed they had won something rather than bought something. Neither of these is a failure of character and neither would stop a sensible person hiring him. Both are the kind of detail that tells a hiring manager how this person's deals are going to be described to them, which is worth knowing before the first one.

An answer that holds up

A pipeline my team depended on was failing every fortnight and it belonged to a team I had no authority over. I brought their lead three months of failure data with the hours attached, which got her attention, and what actually closed it was taking the reporting layer off her backlog and onto my team. That is about a day a week of an analyst's time, ongoing, and it was the price. I told my own team we were getting control of our reporting, which was true and was not the reason. I should have said plainly that I had traded a day a week for reliability, because when that analyst asked six months later why she was maintaining somebody else's dashboards, the honest answer was a decision I had made and dressed up. Failures went from fortnightly to roughly one a quarter, which was worth it. I would make the same trade again and I would describe it accurately to my own team the second time.

The interviewer asks whether she stayed convinced after he left the room.

For about two quarters. When her team got a new mandate the pipeline started slipping again, and it held that time because the reporting layer was ours, not because she was still persuaded.
