Quality Assurance (QA) Engineer Interview Questions

The goal for a successful interview for a Quality Assurance (QA) Engineer is to showcase their ability to plan and execute comprehensive testing strategies, demonstrate their expertise in various testing methods and tools, and prove their proficiency in identifying and resolving defects and issues in software development processes.

Situational interview questions

• You have found a critical defect in a software release, but the deadline for launch is only two weeks away. What steps would you take to ensure that the defect is fixed in time without compromising the quality of the software?
• A stakeholder has reported an issue that cannot be replicated in the development environment. As a QA Engineer, what steps would you take to identify and resolve the issue?
• A tester reports a recurring problem with a feature of a software product that has been previously tested and passed. How would you approach the situation to identify the root cause and ensure that the problem is resolved correctly?
• A customer has reported an issue with the software that cannot be duplicated in-house. What would you do to capture more information about the issue and identify the root cause of the problem?
