This resulted in a higher quality product and reduced negative impact on the company's reputation.

Situational Questions

• 4. You are working on a project with a tight deadline, and your team is experiencing a high defect rate. How do you handle the situation and ensure project success?
  Answer: First, I would identify the root cause of the high defect rate and work with my team to find a solution.

• 8. Can you explain the difference between functional, integration, and system testing?
  Answer: Functional testing focuses on testing individual features or functions of a product. Integration testing verifies that different components of a system work together correctly. System testing is done to assess the entire system's compliance with specified requirements and ensure it meets end-user expectations.
• 9. What is regression testing, and when do you typically perform it?
  Answer: Regression testing is performed to ensure that changes or fixes made to the software do not introduce any new defects or break existing functionality. It is usually performed after every major code change or before a new release.
