Preparing for a QA interview can be challenging, especially when you don’t know which Manual Testing Interview Questions recruiters are likely to ask.
Knowing definitions is not enough anymore.
In a real QA interview, the interviewer may start with a basic question like “What is Software Testing?” and then quickly move to:
“You have only 2 hours before release. What will you test?” “You found a critical bug just before production. What will you do?” “Developer says it is not a bug. How will you handle it?” “What will you do if the requirement is unclear?”
These questions test how you think as a QA Engineer, not just how well you remember testing definitions.
This guide contains 50 carefully structured Manual Testing interview questions, including scenario-based questions and practical ways to answer them confidently in an interview.
💡 Important: Don’t memorize these answers word-for-word. Understand the approach and answer in your own words.
Why Practice Manual Testing Interview Questions?
Practicing Manual Testing Interview Questions helps you revise important testing concepts and prepare clear answers before the actual interview.
📌 How to Answer Manual Testing Questions in an Interview
Before jumping into the questions, remember this simple formula:
Definition → Example → Practical Experience
For example:
Interviewer: What is Regression Testing?
❌ Weak answer:
“Regression testing is testing the existing functionality after changes.”
✅ Stronger answer:
“Regression testing is performed to make sure that existing functionality still works after new changes or bug fixes. For example, if a developer changes the payment module, I would not test only the payment functionality. I would also verify related areas such as checkout, order creation and confirmation because the change could affect existing functionality.”
This makes your answer sound practical rather than theoretical.
These Manual Testing Interview Questions cover basic concepts, real-world scenarios, test cases, defect management, and practical situations that QA professionals may face during interviews.
50 Manual Testing Interview Questions & How to Answer
1. How would you explain Software Testing to a non-technical person?
How to answer:
Don’t give a textbook definition.
Say:
“Software testing is the process of checking whether an application behaves as expected and identifying problems before users encounter them.”
Example:
“If an online shopping application allows users to add products to a cart, I would verify that the correct product, quantity and price are displayed and that checkout works correctly.”
💡 Interview Tip: Use a real-life example whenever possible.
2. What is the difference between Verification and Validation?
How to answer:
A simple way to remember:
Verification → Are we building the product correctly?
Validation → Are we building the correct product?
Example:
“Verification involves reviewing requirements, designs and documents without executing the application. Validation involves executing the software and checking whether it meets user expectations.”
3. What is the difference between QA and Testing?
How to answer:
“QA is broader and focuses on improving the overall quality process, while testing is one activity within that process used to identify defects and verify application behavior.”
Strong interview point:
You can add:
“QA is generally process-oriented, while testing is more product-oriented.”
4. What is SDLC?
How to answer:
“SDLC stands for Software Development Life Cycle. It defines the different stages involved in developing software, such as requirement analysis, design, development, testing, deployment and maintenance.”
Then add:
“QA involvement can start early during requirement analysis rather than waiting until development is complete.”
5. What is STLC?
How to answer:
“STLC stands for Software Testing Life Cycle. It describes the testing activities performed during a software project.”
Typical stages include:
Requirement Analysis
Test Planning
Test Case Development
Test Environment Setup
Test Execution
Defect Reporting
Test Closure
6. What is a Test Scenario?
How to answer:
“A test scenario is a high-level condition or functionality that we want to verify.”
Example:
For a login page:
Verify login with valid credentials
Verify login with invalid credentials
Verify password field behavior
Verify account lockout
7. What is a Test Case?
How to answer:
“A test case contains specific steps, test data, expected results and other information required to verify a particular functionality.”
Example:
Test Case: Verify login with valid credentials.
Steps:
Open login page.
Enter valid username.
Enter valid password.
Click Login.
Expected: User should reach the dashboard.
8. What is the difference between Test Scenario and Test Case?
Simple explanation:
Scenario = What to test
Test Case = How to test
Example:
Scenario: Test login functionality.
Test Cases:
Valid username + valid password
Invalid username + valid password
Valid username + invalid password
Blank username
Blank password
9. What is a Test Plan?
How to answer:
“A Test Plan is a document that defines the testing scope, objectives, strategy, resources, schedule, risks, environments and responsibilities for a testing activity.”
Interview Tip:
If asked whether every project has a formal test plan, don’t blindly say yes.
You can say:
“The level of documentation depends on the organization’s process and project requirements.”
10. What is a Test Strategy?
How to answer:
“A Test Strategy defines the overall testing approach for a project. It can include testing types, environments, tools, risks, automation approach and quality objectives.”
