What's the problem with automatically retrying failed e2e tests?
Short interview answer
A retry that passes hides an intermittent failure that may also affect real users. Retries are acceptable as a safety net against known infrastructure noise, but a consistently flaky test should be diagnosed and fixed, since the flakiness often reflects a real race condition.
Key takeaway
Explain the underlying mental model clearly, then support it with a concrete example and its trade-offs.
