Explanation

Answer Example

In a previous role, a production issue caused our e-commerce platform's checkout process to fail intermittently, resulting in a loss of revenue. I started by reproducing the issue in a staging environment and analyzing server logs to pinpoint the root cause, which turned out to be a race condition in the database transactions. I quickly implemented a temporary fix to serialize database operations and communicated updates to stakeholders throughout the process. For a permanent fix, I refactored the affected code to use a more robust transaction model and added unit tests to prevent regressions. This resolved the issue within 4 hours, and I documented the steps for future reference.
