• 7. Can you walk me through your testing process?
  My testing process starts with analyzing the requirements and understanding the user expectations. Then, I create test cases and execute them, documenting any bugs or issues I encounter. After verifying the fixes, I perform regression testing to ensure previous functionality is not affected. I also conduct exploratory testing to find any undiscovered bugs before release.
• 8. How do you handle a major bug that is blocking the release of a software?
  I immediately communicate the issue with the team and provide all necessary information, such as steps to reproduce and severity. I also provide suggestions for a quick fix, if possible. I work closely with the development team to prioritize and resolve the issue as soon as possible.
• 9. How do you ensure the quality of mobile applications?
  Apart from regular functional, regression and user acceptance testing, I also perform compatibility testing on different devices, browsers, and operating systems. I prioritize testing on the most commonly used devices and consult with the team on any necessary adjustments to ensure the app's compatibility and responsiveness.
• 10. Can you give an example of how you detected a previously undiscovered bug?
  While participating in an exploratory testing session, I decided to try some uncommon user scenarios. During this, I discovered an issue where the application crashed when the user entered a certain combination of data. This bug had not been discovered during regular testing but could have significantly impacted user experience.

Behavioral Questions

• 11. Tell me about a challenging bug you encountered and how you resolved it.
  During a project, I encountered a bug that was causing the application to crash on certain devices. After investigating, I discovered that the issue was related to a third-party library. I worked closely with the development team in researching and testing different solutions until we found one that fixed the issue. We also implemented a more thorough testing process for third-party libraries in future projects.
• 12. How do you manage your time and prioritize tasks?
  I use different productivity tools to create a to-do list and prioritize tasks based on urgency and importance. I also regularly communicate with my team to make sure we are aligned and work together to meet project deadlines.
• 13. Can you tell me about a time when you made a mistake in your work and how you handled it?
  During a testing session, I missed a crucial bug that was discovered by a team member during a code review. I immediately took responsibility for my mistake and made sure to thoroughly review my work from then on. I also implemented a double-checking system with my team to avoid similar mistakes in the future.
• 14. What motivates you to continuously improve your skills as a manual QA tester?
  I am motivated by the ever-changing landscape of technology and the potential for growth and learning in this field. I continuously seek to improve my skills and stay updated with the latest industry trends.
• 15. How do you handle repetitive and monotonous tasks in your job?
  I find ways to make these tasks more interesting, such as creating a checklist or experimenting with different testing techniques. I also make sure to take breaks and alternate between tasks to keep my focus and motivation high.

Situational Questions

• 16. If a feature you were responsible for testing is continuously failing, what steps would you take to troubleshoot it?
  First, I would communicate the issue with the development team and gather as much information as possible. Then, I would review the test cases and logs to ensure I am testing it correctly. I would also try to isolate the issue and test it on different environments to determine if it's caused by a specific system. If all else fails, I would approach the team to discuss potential solutions and implement them accordingly.
• 17. If a project deadline is shifted, how would you adjust your testing process to ensure timely delivery?
  I would reassess all the testing tasks and prioritize based on the new deadline. If necessary, I would discuss with the team to see if we can delegate some of the tasks to ensure timely delivery. I would also make sure to communicate any adjustments with the team and document them for future reference.
• 18. What would you do if you found a critical bug right before a software release?
  I would immediately communicate the issue with the development and project management teams, providing all necessary information and suggestions for a quick fix. I would also suggest delaying the release until the bug is fixed and perform a thorough regression test to ensure the quality of the final product.
• 19. If you receive a customer complaint about a software issue, how do you handle it?
