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.

How would you test a vending machine?
Suppose that we wish to know which stories in a 100-story building are safe to drop eggs from, and which will cause the eggs to break on landing. What strategy should be used to drop eggs such that total number of drops in worst case is minimized and we find the required floor. We may make a few assumptions: An egg that survives a fall can be used again. A broken egg must be discarded. The effect of a fall is the same for all eggs. If an egg breaks when dropped, then it would break if dropped from a higher floor. If an egg survives a fall then it would survive a shorter fall.

What's the worst thing about Quality Assurance?
Most of the questions were things like, "You work for a company that manufactures blenders. How do you test this blender?" They're basically looking for you to consider every possible angle in which you would test this product-- Who's the user, what's your company's warranty, how does it handle standard products, how well does it make a milkshake, how does it handle rocks if you put them in there, should it handle rocks, etc. They also asked me to test an office printer, an ATM machine, and a web browser. The coding questions I was asked were things like, "Given an unsorted array with n elements where every element except for one is duplicated in the array, how do you find the unique element?"
Given an array of ints where all values are duplicated except for one, find the value of the element that isn't duplicated. (e.g. [1, 3, 5, 6, 3, 1, 6] would return 5)
