“Describe a time you had to persuade someone.”
Influence without authority is a critical skill. Interviewers want to see that you can build a compelling case, understand other perspectives, and drive alignment — not just push harder.
STAR with emphasis on understanding their perspective first, then your approach to building the case.
Use STAR. Show you understood their perspective before making your case.
Example: 'Our engineering lead was resistant to adding A/B testing infrastructure — he felt it was premature and would slow down shipping. I needed to get his buy-in to move the roadmap forward.
Before pushing my view, I spent an hour understanding his objections. His core concern was that we'd over-engineer it and spend a sprint on infrastructure with no immediate payoff. That was fair.
I came back with a proposal that directly addressed that: a lean version that would take 3 days, not a sprint, and a clear example of a decision we'd gotten wrong the previous quarter that A/B testing would have caught. I connected the cost of that mistake to the cost of the infrastructure.
He agreed to the lean version. It shipped in 3 days. Within 6 weeks, it had already changed two major product decisions. He became the biggest advocate for expanding it.'
