Tell me about a time you disagreed with an engineer about a design decision

What They’re Really Asking

Can you navigate cross-functional conflict while prioritizing user needs and business goals?

Strong Sample Answer

At Meta, I pushed back on an engineer who wanted to compress a newsfeed card to improve load time. Using Figma, I prototyped both versions and ran a 50-user A/B test on UserTesting. The compressed version increased load speed by 15% but reduced content comprehension by 22%, measured via recall quizzes. I presented data showing the full card led to 30% higher engagement and shared research on attention spans. We compromised: lazy-loaded images behind a skeleton screen, cutting load time by 10% while preserving comprehension. Engagement rose 18% with no drop in retention. That taught me to anchor disagreements on user data, not opinion.
