I have experience with manual and automated testing processes and have worked on both web and mobile applications.
• 2. How important is communication in the QA process?
  Communication is a crucial aspect of the QA process. It is essential for the QA tester to have strong communication skills to effectively communicate issues and bugs to the development team. This helps ensure that the issues are resolved efficiently and the quality of the product is not compromised.
• 3. How do you prioritize testing tasks?
  Prioritizing testing tasks is crucial to ensure that the most critical features of a product are thoroughly tested. I prioritize testing tasks by collaborating with the development team and identifying the most critical and high-risk areas of the product. I also take into consideration the project timeline and any client requirements.
• 4. How do you handle a disagreement with a developer about a reported bug?
  In such a situation, I would first try to understand and gather more information about the bug by discussing it with the developer. If we still do not agree, I would escalate the issue to our project manager or another senior member of the team to mediate and come to a resolution.
• 5. How do you ensure that test cases are thorough and cover all aspects of a feature?
  To ensure thorough test coverage, I first review the requirements and design documents to understand all aspects of the feature. I then create test cases that cover all possible scenarios and edge cases. I also perform exploratory testing to identify any unexpected behaviors or bugs.

Technical Skills & Experience

• 6. What is the difference between functional and non-functional testing?
  Functional testing verifies if a software product meets its functional requirements, while non-functional testing checks its performance, security, usability, and other non-functional aspects. Non-functional testing ensures that the product functions correctly and efficiently in real-world scenarios.
• 7. How do you perform regression testing?
  Regression testing involves testing the previously developed and tested features to ensure that new changes or bug fixes have not adversely affected them. I use a combination of manual and automated testing techniques to perform regression testing. I also maintain a regression test suite to make the process more efficient.
• 8. Can you explain the difference between white-box and black-box testing?
  White-box testing involves testing the internal workings of a software product, while black-box testing tests its functionality without any knowledge of the internal code. White-box testing is typically performed by developers, while black-box testing is done by QA testers.
• 9. How do you handle testing on multiple platforms and devices?
  With the increasing popularity of mobile and web applications, it is essential to test a product on multiple platforms and devices. I use a combination of manual and automated testing techniques to ensure compatibility on different platforms and devices. I also collaborate with the development team to understand any device-specific functionalities.
• 10. How do you ensure that your test cases are well-maintained and up-to-date?
  I regularly review and update my test cases to ensure they remain relevant and effective. Whenever there are changes in the product requirements, I update the test cases accordingly. I also regularly discuss with the development team to understand any new changes or updates that can affect the existing test cases.

Behavioral Questions

• 11. Can you tell us about a time when you had to work under pressure to meet a strict deadline?
  In my previous job, we had a last-minute change in project requirements that required thorough testing before the release. I had to work overtime and prioritize my tasks to ensure everything was tested before the deadline. I communicated clearly with the team and was able to complete all the testing and meet the deadline successfully.
• 12. How do you handle a situation when you disagree with a team member?
  I believe in open communication and mutual respect among team members. If I disagree with a team member, I try to understand their perspective and discuss the issue calmly. I believe that everyone's opinions should be taken into consideration and if a disagreement cannot be resolved, it should be escalated to the appropriate authority.
• 13. Can you give an example of a time when you had to troubleshoot a complex issue?
  In my previous project, there was a complex issue that affected the performance of the application on a specific device. It took a lot of analysis and collaboration with the development team to identify the root cause of the issue and come up with a solution. I learned the importance of patience and persistence in troubleshooting complex issues.
• 14. How do you stay updated with the latest industry practices and tools?
  I regularly attend seminars and workshops related to quality assurance in software development. I also follow industry experts and blogs to stay up-to-date with the latest trends and practices in the QA field. I am always eager to learn and adapt to new tools and techniques that can improve my testing skills.
• 15. Can you tell us about a time when you had to step outside of your role to ensure the success of a project?
  In my previous project, we had a tight deadline and a team member fell ill. I was asked to step in and carry out some of their tasks to ensure the project was delivered on time. I was able to take on the additional responsibilities without compromising on the quality of my own tasks and helped the team meet the deadline successfully.

Situational Questions

• 16. How would you prioritize testing tasks if there are limited resources and time for testing?
  In such a scenario, I would prioritize testing tasks by identifying the most critical and high-risk features of the product. I would also communicate with the development team and stakeholders to understand their priorities and make a plan based on their inputs. If necessary, I would also prioritize tasks based on the impact of potential bugs on end-users.
• 17. How would you handle a situation where a feature behaves unexpectedly, but there is a disagreement on whether it is a bug or not?
