"Tell me about a time you disagreed with a teammate."
Meta values direct communication. Your answer should show:
You raised the concern directly (not behind their back). You listened to their perspective. You found a resolution based on data or user impact.
Weak: "We disagreed but eventually compromised." This is vague.
Strong: "I disagreed with our tech lead about using SQL vs NoSQL. I ran benchmarks on our workload, showed that writes were x faster with NoSQL at our scale, and we agreed on a -week pilot. The pilot confirmed NoSQL was the right choice."
