Describe a situation where you had to convince a team to abandon work they were invested in.
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.
On a security migration where I led ~20 engineers, one team had spent 6 weeks building a custom data lineage tracking system. While evaluating it in the restricted target environment, I realized it relied on metadata APIs that wouldn't be available post-migration; refactoring would take another 8 weeks we didn't have.

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.
How would you architect a data lineage system that survives migration to a restricted environment? What APIs should you depend on and which should you avoid?
What's your evaluation criteria for adopting an open-source lineage tool vs building custom? Walk through the specific dimensions.
