The fifth story stands alone because it is the one most candidates fake
Sketch your own 'time I was wrong' infra story in four beats (stakes, your decision, what the evidence showed, what you changed), then check that the failure is real and the contribution is first-person.
Step 1 of 2
The fifth story stands alone because it is the one most candidates fake. A real time-I-was-wrong is the highest-value thing you can bring.
“I argued hard for active-active across two regions to cut p99 for our far-edge users. We shipped it and the split-brain risk on our stateful path turned out to cost more in on-call and data-reconciliation pain than the latency win was worth. The data changed my mind: I moved us to active-passive with fast failover and put the latency budget into edge caching instead. I was wrong about where the impact was and the metrics told me before my pride did.”
