Failure and learning
Choose a real miss and explain the correction.
Understand the problem
Describe the warning signs you missed, the effect on others, and the mitigation. Distinguish the immediate repair from the process or technical change that prevented recurrence.
Make it concrete
An unbounded worker rollout overloads a database; mitigation reduces concurrency and prevention adds load tests and admission limits.
Trade-offs and pitfalls
Blaming others or disguising a strength as a failure removes useful evidence.
Check your understanding
State what you would do differently before the incident began.
