Why interviewers ask this
This question, common in cross-functional and senior individual-contributor roles, assesses whether you can genuinely persuade and align people who do not report to you, since much real organisational work depends on this kind of influence rather than formal hierarchy alone. Interviewers want a specific example of real persuasion, not simply asking politely and being agreed with immediately.
Choosing the right example
Pick a genuine example where you needed buy-in from a peer, another team, or someone senior to you, and where there was real, initial resistance or disagreement you had to work through, rather than an example where everyone was already aligned from the start.
How to structure your answer
Briefly explain what you needed the other person or team to do and why, describe the specific approach you used to build genuine understanding and buy-in (data, relationship-building, addressing their concerns directly), and close with the outcome and what it taught you about influencing effectively.
