Tell me about a time you had a difficult cross-team relationship and how you overcame it.
Behavioral rounds at FAANG and AI labs now include 1-2 design follow-ups. Each answer below ships with both.
The situation, your role, and the stakes, compressed.
I was building an anomaly detection platform that needed to integrate with the platform team's paging system for top business metrics. They flat-out resisted. Their on-call had been burned by prior ML alert floods, and they didn't trust a new ML system would be different. Without their buy-in, the platform was dead regardless of model quality.

Design Follow-Ups
The new behavioral roundBehavioral rounds increasingly drop into 1-2 technical follow-ups that probe whether you could actually build the system you described. These are the design questions a real interviewer would ask after this STAR answer.
Design the alert inhibition system. How does it technically prevent cascades, and what's the data model for inhibition rules?
How would you architect the shadow-then-promote rollout pipeline? Walk through the gates, metrics, and human-in-the-loop checkpoints.
