  My first step would be to report the bug to the development team and project manager, emphasizing the potential impact on the user experience and business if the bug is not fixed. I would provide suggestions for a quick fix or a work-around solution to mitigate the issue. If the bug cannot be resolved before the release date, I would escalate the issue to senior management and recommend delaying the release to ensure a high-quality product is delivered.

Technical Knowledge

• 9. Can you explain the difference between functional and non-functional testing?
  Functional testing ensures that individual features of a software are working as expected, while non-functional testing evaluates the performance, security, and usability of the software as a whole. Functional testing is typically done through black box testing techniques, while non-functional testing may require white box or grey box testing methods.
• 10. What is boundary value analysis and equivalence partitioning?
  Boundary value analysis is a test design technique that involves testing the boundaries of input values, both at the minimum and maximum range, as well as just inside and outside those boundaries. Equivalence partitioning is a test design technique where test cases are designed to cover each partition or group of inputs that are expected to be processed the same way by the software. Both techniques help identify bugs in the boundary conditions and potential errors in processing input values.
• 11. How would you handle testing for compatibility across different browsers and devices?
  To ensure compatibility, I would use a mix of manual testing and automated testing tools to cover the most common browsers and devices used by our target audience. For manual testing, I would follow a set list of test cases on different browsers and devices to identify any bugs or inconsistencies. For automated testing, I would use cross-browser testing tools like Selenium or TestComplete to run tests on multiple browsers and devices simultaneously, reducing the time and effort needed for testing.
• 12. How do you handle testing for security vulnerabilities?
  Security testing is an essential part of the testing process, and I would start by reviewing any security requirements established by our organization or the client. I would then use manual and automated techniques to identify potential security risks, including penetration testing, input validation testing, and stress testing. I would also work closely with our security team to understand any past vulnerabilities and take necessary precautions to prevent future issues.
