Describe a time when you had to push a project forward despite significant obstacles or resistance.
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 the technical lead on an org-wide security migration that affected 20+ engineers and dozens of production pipelines. Security requirements were non-negotiable but the migration was painful: workflows would break, new tools had to be learned, productivity would dip.

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.
Walk me through the migration tooling that reduced per-team work by ~60%. What was actually in the templates?
The data lineage rebuild was the painful part you frontloaded. Design it: what to track, how to query, what to expose to teams.
