Clear understanding of manual testing fundamentals
Knowledge of STLC and SDLC
Ability to write and execute test cases
Log clear and reproducible defects
Understand Agile/Scrum basics
Exposure to JIRA, Postman, SQL
Basic awareness of automation & performance testing
Good communication with developers and leads

2. Core Interview Questions & Structured Answers (Technical Round)

1. What is software testing?

Software testing is the process of verifying and validating that a software application works as expected, meets requirements, and is free from critical defects before release.

2. Why is software testing important?

Ensures product quality
Identifies defects early
Reduces cost of fixing issues
Improves customer satisfaction

3. What is the difference between verification and validation?

Verification	Validation
Static process	Dynamic process
Reviews & inspections	Actual testing
“Are we building it right?”	“Are we building the right product?”

4. Explain SDLC phases

Phase	Description
Requirement	Business needs gathering
Design	System & UI design
Development	Coding
Testing	Validation
Deployment	Release
Maintenance	Bug fixes

5. Explain STLC phases

Requirement analysis
Test planning
Test case design
Test environment setup
Test execution
Test closure

6. What types of testing do you know?

Functional testing
Smoke testing
Sanity testing
Regression testing
System testing
UAT testing

7. Smoke vs Sanity testing

Smoke	Sanity
Broad coverage	Narrow coverage
Build stability	Bug fix verification
Before detailed testing	After changes

8. What is a test case?

A test case is a set of steps, data, and expected results used to verify a specific requirement.

9. Components of a test case

Test case ID
Test scenario
Preconditions
Steps
Test data
Expected result
Actual result
Status

10. What is a bug/defect?

A defect is a deviation between expected and actual behavior of the application.

11. Defect life cycle

Status	Description
New	Logged by tester
Assigned	Assigned to dev
Open	Dev working
Fixed	Issue fixed
Retest	Verified by tester
Closed	Successfully resolved
Reopened	Issue persists

12. Severity vs Priority

Severity	Priority
Impact on system	Urgency to fix
Set by tester	Set by product
Technical	Business

13. What is regression testing?

Regression testing ensures that existing functionalities still work after new changes or bug fixes.

14. What is UAT?

User Acceptance Testing is done by business users to verify the system meets business needs.

15. What is exploratory testing?

Testing without predefined test cases using tester’s experience and understanding.

3. Agile & Process Interview Questions

16. What is Agile?

Agile is an iterative development approach focusing on continuous delivery, collaboration, and feedback.

17. What is a sprint?

A sprint is a fixed time-box (usually 2 weeks) in which a set of features are developed and tested.

18. Agile ceremonies you know

Sprint planning
Daily stand-up
Sprint review
Retrospective

19. What is a user story?

A user story describes functionality from an end-user perspective.

Example:
As a user, I want to reset my password so that I can regain access.

20. What are acceptance criteria?

Conditions that must be met for a user story to be accepted.

4. Scenario-Based Interview Questions with RCA

21. Login works for valid user but fails for some users. What will you check?

User roles
Database records
Environment config
Logs

RCA Example:
Some users marked as inactive in DB.

22. A bug you reported was rejected. What will you do?

Re-check steps
Validate requirement
Attach screenshots/logs
Discuss with dev politely

23. Application crashes when uploading large file. What could be the reason?

File size validation missing
Memory issue
Server timeout

24. Real-Time Defect Example

Issue: Submit button enabled without mandatory fields
Severity: Medium
Root Cause: Missing front-end validation

5. Test Case Examples

UI Test Case – Login Page

Field	Value
Scenario	Valid login
Steps	Enter valid username & password
Expected	Navigate to dashboard

API Test Case – Login (Postman)

POST /login

{

“username”: “testuser”,

“password”: “pass123”

}

Expected Result:
Status 200, token generated

Database Validation (SQL)

SELECT status

FROM users

WHERE username = ‘testuser’;

Used to validate backend user status.

Performance Test Example (Basic)

50 users login simultaneously
Response time < 3 seconds
