Quality Assurance Tester Interview Question:

During my previous role as a Quality Assurance Tester, I encountered a critical bug in a software application that impacted the user experience. The bug caused the application to crash when users attempted to save their work, resulting in potential data loss.

Upon discovering the bug, I immediately documented the issue by meticulously recording the steps to reproduce it. I then communicated the bug to the development team with clear and concise details of the expected behavior and actual behavior encountered.

To further investigate the root cause of the bug, I conducted thorough regression testing to identify any potential related issues. I also collaborated with the developers to discuss possible solutions and prioritize the bug fix based on its impact on the application's functionality.

Once a fix was implemented, I thoroughly tested the solution to ensure the bug was successfully resolved. I re-tested the affected functionality and performed additional test cases to verify that the fix did not introduce any new bugs.

By approaching the resolution process in a systematic and collaborative manner, I was able to effectively address the critical bug and prevent potential issues from affecting end-users.
