Qa Engineer Interview Questions

In a QA Engineer interview, expect questions that test your understanding of the software testing process. While most questions will test your competency, the interviewer may also want to see that you can build a high-level strategy for preventing and resolving bugs and defects.

Top QA Engineer Interview Questions & How To Answer

Question 1

Question #1: What is the difference between quality assurance, quality control, and software testing?

How to answer
How to answer: With this question, you can demonstrate an understanding of how these tasks are interrelated. Mention that quality control is where test results are analyzed and defects are identified, whereas quality assurance refers to the preparation of product standards and requirements. Testing is when the final product is checked for vulnerabilities.
Question 2

Question #2: Describe positive and negative testing.

How to answer
How to answer: The interviewer likely wants to see that you comprehend the importance of negative testing. Explain that positive testing ensures that the product works correctly, while negative testing ensures that if the user inputs invalid information, the product will respond accordingly. You may consider sharing a hypothetical example of a time when negative testing would be particularly valuable in identifying a bug during production.
Question 3

Question #3: What is build and release?

How to answer
How to answer: With this question testing your technical skills, you can display your mastery of the quality assurance process from start to finish. A successful answer would clarify that build is when software is handed over from the development team to the testing team, while release is when software is handed over to the user.
