Why this question matters
Conflicting priorities are normal. The question is whether the candidate silently multitasks, complains, or helps create a decision.
I had a week where I was expected to finish a feature, review a migration, and help investigate a production slowdown. I made the conflict visible instead of trying to do all three badly. I listed the impact and urgency of each item: the production slowdown affected users now, the migration could block release if wrong, and the feature had some schedule flexibility. I proposed focusing on the incident first, reviewing the migration next, and moving the feature by a day.
