Interviews for manual testing aim to determine thought processes and testing techniques. Defect finding is based on clarity, logic, and reasoning. People fail in interviews because of their inability to think and reason, no matter how many answers they’ve memorized.
This is a comprehensive resource on key questions you’ll need to be ready for, be simple with some explanations. It has a structure based on some real-world scenarios, suggestions, and answers you can use in interviews.
What do interviewers expect in manual testing roles?
Interviewers usually check these skills:
- Clear understanding of testing basics
- Ability to write and execute test cases
- Bug reporting skills
- Logical thinking
- Communication
If you explain answers with examples, your chances improve.
Basic manual testing interview questions
1. What is manual testing?
Manual testing means testing software by executing test cases without automation tools. You act like an end user and check if the system works correctly.
Example: You test a login page by entering valid and invalid inputs.
2. What is SDLC?
Software Development Life Cycle defines how software is built.
Main phases:
- Requirement gathering
- Design
- Development
- Testing
- Deployment
- Maintenance
3. What is STLC?
Software Testing Life Cycle defines testing steps.
Steps include:
- Requirement analysis
- Test planning
- Test case design
- Test execution
- Defect reporting
- Test closure
4. What is a test case?
A test case is a set of steps to verify a feature.
Example:
- Open login page
- Enter valid username
- Enter valid password
- Click login
- Check dashboard loads
5. What is a defect?
A defect is a mismatch between expected and actual results.
Example: The system shows errors even with valid login.
6. What are types of testing?
Common types:
- Functional testing
- Regression testing
- Smoke testing
- Sanity testing
- Usability testing
7. What is black box testing?
You test functionality without seeing code.
8. What is white box testing?
You test internal logic and code structure.
9. What is regression testing?
You test existing features after changes.
Example: After adding a new feature, check if old features still work.
10. What is a test plan?
A test plan defines scope, approach, resources, and timeline.
Intermediate manual testing interview questions
11. What is severity and priority?
Severity shows impact.
Priority shows urgency.
Example:
- App crash is high severity
- Typo is low severity
12. What is the bug life cycle?
Steps include:
- New
- Assigned
- Open
- Fixed
- Retested
- Closed
13. What is exploratory testing?
You test without predefined test cases. You explore and learn the system.
14. What is boundary value analysis?
You test edge values.
Example
If input range is 1 to 100:
- Test 0
- Test 1
- Test 100
- Test 101
15. What is equivalence partitioning?
You divide inputs into groups and test one value from each group.
Example
Age field:
- Valid group: 18 to 60
- Invalid group: below 18
16. What is smoke testing?
You test basic functions to check if the build is stable.
17. What is sanity testing?
You test specific functionality after small changes.
18. What is test coverage?
It measures how much of the application you tested.
19. What tools do you use?
Common tools:
- JIRA for bug tracking
- TestRail for test cases
- Excel for simple tracking
20. What is a test scenario?
A high level idea of what to test.
Example
- Test login functionality.
- Advanced manual testing interview questions
21. How do you prioritize test cases?
Use these factors:
- Business impact
- Risk
- Usage frequency
Example: The login feature gets the highest priority.
22. How do you handle a rejected bug?
Steps:
- Recheck the issue
- Collect proof
- Share logs and screenshots
- Discuss with developer
23. How do you test without documentation?
Use:
- Exploratory testing
- Previous experience
- User flows
24. What is risk based testing?
You test areas with higher risk first.
Example: Payment module has higher risk than profile page.
25. How do you ensure full test coverage?
Use:
- Requirement Traceability Matrix
- Test scenarios for each requirement.
26. What is alpha testing?
Internal testing before release.
27. What is beta testing?
Testing by real users.
28. How do you test a login page?
Test cases:
- Valid login
- Invalid login
- Empty fields
- Password masking
- SQL injection
- Session timeout
29. What is negative testing?
You test invalid inputs.
Example: Enter letters in the numeric field.
30. How do you write a bug report?
Include:
- Title
- Steps to reproduce
- Expected result
- Actual result
- Screenshots
Scenario based manual testing interview questions
Conclusion
Consider your ability to think and respond like a tester when answering manual testing interview questions. Ideas, examples, and experiences help justify your answer. Consistent practice and imaginative thinking improve your skills.
