1. Role Expectations – Tester with 1.5 Years Experience
At 1.5 years of experience, you are expected to move beyond fresher-level dependency and work as a junior-to-mid QA engineer who can independently test assigned features.
What interviewers expect at this level:
- Strong fundamentals of manual testing
- Clear understanding of STLC and SDLC
- Ability to analyze requirements and write test cases
- Hands-on experience in functional, regression, smoke, sanity testing
- Clear and professional bug reporting
- Basic understanding of Agile/Scrum
- Exposure to API testing, SQL validation
- Awareness of automation and performance testing
- Good communication with developers and leads
2. Core Testing Interview Questions & Structured Answers
1. What is software testing?
Software testing is the process of verifying and validating that a software application meets business requirements and works as expected, while identifying defects before release.
2. Why is software testing important?
- Ensures product quality
- Prevents production failures
- Reduces cost of fixing defects
- Improves customer satisfaction
- Builds confidence in releases
3. Explain SDLC and tester involvement
| SDLC Phase | Tester Role |
| Requirement | Requirement understanding & review |
| Design | Identify test scenarios |
| Development | Prepare test cases |
| Testing | Execute tests & log defects |
| Deployment | Sanity testing |
| Maintenance | Regression testing |
4. Explain STLC in detail
STLC defines the testing lifecycle:
- Requirement analysis
- Test planning
- Test case design
- Test environment setup
- Test execution
- Test closure
At 1.5 years, interviewers expect you to understand what you actually do in each phase, not just definitions.
5. Difference between verification and validation
| Verification | Validation |
| Static activity | Dynamic activity |
| Reviews & walkthroughs | Actual testing |
| Are we building it right? | Are we building the right product? |
6. What types of testing have you performed?
- Functional testing
- Smoke testing
- Sanity testing
- Regression testing
- System testing
- Basic UAT support
7. Smoke testing vs Sanity testing
| Smoke Testing | Sanity Testing |
| Build stability check | Bug-fix verification |
| Broad coverage | Narrow & focused |
| Done before deep testing | Done after minor changes |
8. What is a test case?
A test case is a documented set of steps, test data, and expected results used to validate a specific requirement.
9. Components of a test case
- Test Case ID
- Scenario
- Preconditions
- Test Steps
- Test Data
- Expected Result
- Actual Result
- Status
10. How do you write effective test cases?
- Understand business flow
- Cover positive & negative scenarios
- Include boundary conditions
- Write clear and reusable steps
11. What is a defect (bug)?
A defect is a deviation between the expected behavior and the actual behavior of the application.
12. Explain defect life cycle
| Status | Description |
| New | Logged by tester |
| Assigned | Assigned to developer |
| Open | Developer working |
| Fixed | Bug fixed |
| Retest | Tester verifies |
| Closed | Issue resolved |
| Reopened | Issue still exists |
13. Severity vs Priority
| Severity | Priority |
| Impact on system | Urgency to fix |
| Set by tester | Set by product |
| App crash | Business-critical issue |
14. What makes a good bug report?
- Clear summary
- Step-by-step reproduction
- Actual vs expected result
- Screenshots/logs
- Correct severity & priority
3. Agile & Process Interview Questions
15. What is Agile testing?
Agile testing is continuous testing aligned with sprint-based development, focusing on early feedback and faster delivery.
16. What is a sprint?
A sprint is a fixed time-box (usually 1–2 weeks) in which development and testing of selected user stories are completed.
17. Agile ceremonies you have attended
- Sprint planning
- Daily stand-up
- Sprint review
- Retrospective
18. What is a user story?
A user story describes a feature from the user’s perspective.
Example:
As a user, I want to change my password so that my account remains secure.
19. What are acceptance criteria?
Acceptance criteria define the conditions that must be met for a user story to be considered complete.
4. Scenario-Based Interview Questions with RCA
20. Login works for some users but fails for others. What will you check?
- User role/status
- Database records
- Environment configuration
- Application logs
RCA Example:
Some users were marked inactive in the database.
21. A defect you logged was rejected. How do you handle it?
- Re-test the scenario
- Re-check requirements
- Attach screenshots/logs
- Discuss politely with developer
22. Application crashes while uploading a large file. RCA?
- File size validation missing
- Memory limitation
- Timeout handling issue
23. Real-Time Defect Example
Issue: Submit button enabled without mandatory fields
Severity: Medium
RCA: Missing front-end validation
5. Real-Time Project Defects & RCA Examples
Banking Application
- Defect: Incorrect balance after fund transfer
- RCA: Cache not refreshed after DB update
Insurance Application
- Defect: Policy created without document upload
- RCA: Backend validation missing
ETL Project
- Defect: Data mismatch in reports
- RCA: Date format conversion issue
6. Test Case Examples
UI Test Case – Login Page
| Field | Value |
| Scenario | Valid login |
| Steps | Enter valid credentials |
| Expected | User navigates to dashboard |
API Test Case – Login
Using Postman:
POST /login
{
“username”: “testuser”,
“password”: “pass123”
}
Expected: HTTP 200, token generated
Database Validation (SQL)
SELECT status
FROM users
WHERE username = ‘testuser’;
