Quality assurance (QA) is the process of verifying whether a product or service meets the requirements and specifications of the customer or user. QA defines a set of rules or requirements for developing a product or service; the product or service needs to meet those requirements, increasing production efficiency and improving customer confidence in the product. QA’s primary goal is to resolve and track issues before releasing a product to customers. QA is a process-driven approach that defines goals and rules for product design, development, and production, improving a team’s processes and efficiency and ultimately enabling a company to compete with others in the industry.
QA rules and standards will change frequently and must meet ISO standards. It is essential in reaching a product from design to deployment, and there are many hot job openings for QA positions. So we will discuss different topics and scenarios one might face during an interview for a Quality Assurance role, with real-world examples.
In this article, we will discuss the top QA Interview Questions.
If you are looking for a job related to QA, you need to prepare for the 2026 QA Interview Questions. Every Interview is indeed different depending on the job profile. Here, we have prepared the critical QA Interview Questions and Answers to help you succeed in your Interview.
QA Interview Questions and Answers for Freshers
This 2026 QA Interview Questions article will present the ten most important and frequently asked QA Interview questions. There are two parts that divide the questions:
Part 1 – QA Interview Questions (Basic)
This first part covers basic QA Interview Questions and Answers.
Q1. What is the difference between Build and release?
Answer:
The development or testing team assigns a number to the installable or executable software that is ready for use, known as a Build, whereas a Release is a number assigned to the installable or executable software delivered to the customer. At the same time, a release is defined as the number provided to the installable or executable software delivered to the customer by the developer or tester.
Q2. Explain the life cycle of a Bug or Bug cycle.
Answer:
The bug cycle includes the following defined steps:
- The user creates a bug with all the necessary details and then assigns it to the corresponding team or person, with the status set to open.
- The corresponding team or person will verify the bug and change the status to accepted if it is a valid bug; otherwise, change it to not valid and close the bug with an appropriate message.
- Based on the bug’s priority, developers will decide whether to fix the bug in this release or the next release.
- If the bug already exists, then the developer closes the bug with the status as a duplicate.
- When the developer starts working on the bug and changes the status of the bug to in progress.
- When the developer fixes the bug, they will change the status to fixed and assign it to a tester for verification.
- The tester verifies the fix; after resolving the bug, close its status; otherwise, update the bug with observations.
Let us move to the following QA Interview Questions.
Q3. What are all the software quality practices throughout the software development cycle?
Answer:
The software quality practices that are being used or followed in the process of the software development cycle are
- We are reviewing the project requirements before the development phase.
- Code reviews are conducted once the development phase is complete.
- Developing test cases to validate the developed code.
- Perform different types of testing, such as session-based testing, Risk-based testing, etc.
- Prioritize the bugs based on the requirements.
- Form a dedicated team for security-related testing and performance testing of a product.
- Perform the regression cycle for all test cases and run the sanity test cases in the production environment.
- Simulate the customer environment in production, run sanity checks, and generate the software QA reports or analysis.
Q4. What is the test-driven development rule?
Answer:
This is a basic QA interview question. The basic rule of test-driven development is to have a test plan and test cases ready before developing the product or writing the code. Before developing its corresponding module, the team will create test cases.
Q5. When to choose automation testing over manual testing?
Answer:
The choice between automation testing and manual testing will be based on different factors, such as
- the frequency of use of a particular test case
- How much time does it take to run manually and to run by a script
- Reusability of the automation script
- The adaptability of the test cases for automation
- The development of the automation script and the effort required to use the automation tool.
Part 2 – QA Interview Questions (Advanced)
Let us now have a look at the advanced QA Interview Questions.
Q6. What is the difference between QA, QC, and software testing?
Answer:
We must follow the planned, systematic monitoring of process quality defined in the quality assurance process to produce a quality product or service. QA enables us to track the progress and outcomes and adjust the process to meet expectations.
Quality control helps identify bugs or defects and ensures the implementation of defined improvements and processes.
Software testing is the process of ensuring that the product meets the customer’s requirements, with the main aim of finding and fixing bugs before release.
Q7. What is a test harness?
Answer:
The test harness is the collection of software and test data required to verify the application by running it under different conditions and environments, such as stress, load, and data-driven testing, and monitoring the results. The test harness has two parts: a test execution engine and a test script repository.
Let us move to the following QA Interview Questions.
Q8. Define test stub and test driver.
Answer:
The test stub will be a call from the software component under test and will be used in a top-down approach.
The test driver will call the component to be tested, using a bottom-up approach.
Q9. How should validation activities be conducted?
Answer:
This is the most-asked QA interview question. Validation activities can be conducted by hiring third-party validation engineers for verification and validation, involving internal team members who are not participating in validation activities, or by conducting an independent evaluation of the product, such as by customers.
Q10. What are the different testing levels when testing any product?
Answer:
There are four types of testing levels when testing any product, as follows:
- Component-level testing
- System-level testing
- Integration testing: checks the interaction between the modules
- Acceptance testing: Here, the customer or user expects a specific output for a given input.
Conclusion
I hope you will understand these concepts well, and I suggest you review your projects, your role in them, and the testing process followed in your company. It will be helpful for the QA interview, and I wish you the best of luck with it.
