41. What if the developer fixes one bug but introduces another?
Answer:
“I would first verify the original defect. Then I would test the affected functionality and related areas to identify regression issues. I would report the new defect separately with clear evidence and update the testing status accordingly.”
42. What if the developer asks you to close a bug that you believe is still valid?
Answer:
Stay professional.

“I would explain why I believe the defect is still valid and provide evidence against the expected requirement. If there is disagreement, I would involve the BA, Product Owner or appropriate stakeholder to confirm the expected behavior.”
Key lesson:
Don’t turn a defect discussion into a personal argument.
43. What if you disagree with another tester?
Answer:
“I would first understand their reasoning and compare it against the requirement and expected business behavior. If we still disagree, I would involve the appropriate stakeholder rather than making the discussion personal.”
This demonstrates teamwork and maturity.
44. What will you do if a developer gives you a build without release notes?
Answer:
“I would ask for the build details and information about the changes included in the build. If there is no formal release note, I would at least confirm the changed areas, known issues and dependencies before starting detailed testing.”
Why?
Because testing an unknown build without understanding changes can lead to poor prioritization.
45. What is your approach when testing a new feature?
Strong answer:
“First, I understand the requirement and business objective. Then I identify test scenarios, clarify ambiguities, prepare test data, design positive and negative test cases, execute them, report defects and perform retesting and regression testing after fixes.”
You can summarize:
Understand → Analyze → Design → Execute → Report → Retest → Regression
46. How do you ensure sufficient test coverage?
Answer:
I consider:
- Requirement coverage
- Positive scenarios
- Negative scenarios
- Boundary conditions
- Business rules
- User roles
- Integrations
- Error handling
- Compatibility
- Regression impact
Strong interview statement:
“I don’t measure coverage only by the number of test cases. I also look at whether important business risks and requirements are adequately covered.”
47. What metrics do you track as a QA Engineer?
Answer:
Depending on the project, useful metrics can include:
- Test cases planned
- Test cases executed
- Pass/fail percentage
- Defects by severity
- Defect rejection rate
- Defect reopen rate
- Defect leakage
- Test execution progress
- Automation coverage, if applicable
Important:
Don’t simply list metrics.
Explain:
“Metrics should help the team understand quality and risk rather than just create numbers.”
48. How do you handle testing when requirements keep changing?
Answer:
“First, I assess the impact of the change on existing requirements and test cases. I update affected test scenarios and communicate the impact on scope and timeline. I then prioritize testing based on business risk and the latest approved requirement.”
Strong addition:
“I also make sure that everyone is aligned on which requirement version is currently valid.”
49. What would you do if the testing deadline is unrealistic?
⭐ Real-World QA Question
Don’t say:
“I will work overtime and finish everything.”
Instead:
“I would communicate the risk early and discuss the available time, scope and priorities. I would suggest risk-based testing and prioritize critical business workflows and recently changed areas. I would clearly communicate what has been tested, what remains, and the associated risks.”
Excellent QA communication:
“I can take this up, but given the available time, which area should we prioritize?”
That sounds professional—not like an excuse.
50. Why should we hire you as a Manual QA Engineer?
⭐ The Final Interview Question
Don’t give a generic answer like:
“Because I am hardworking and a quick learner.”
Instead, connect your strengths to the role.
Sample answer:
“I believe I can contribute because I approach testing from both a user and business perspective. I focus on understanding requirements, identifying risks, designing meaningful test scenarios, reporting defects clearly and collaborating with developers and stakeholders to resolve issues. I also continuously improve my technical skills so I can become more effective as a QA professional.”
Then add something specific from your experience.
For example:
“In my previous project, I was responsible for testing critical workflows and coordinating defect resolution with the development team. That experience helped me become more systematic in identifying risks and communicating them clearly.”
🎯 Bonus: The 7-Step Formula for Scenario-Based QA Questions
When an interviewer gives you a situation, don’t panic.
Use this structure:
1. Understand
What exactly is the problem?
2. Reproduce
Can I reproduce the behavior?
3. Analyze
What functionality and users are affected?
4. Prioritize
How serious and urgent is it?
5. Communicate
Who needs to know?
6. Test
What scenarios should be verified?
7. Follow Up
Retesting + regression + closure.
This framework can help you answer many unfamiliar QA scenarios.
🚨 Common Mistakes Candidates Make in Manual Testing Interviews
❌ Mistake 1: Giving only definitions
The interviewer wants to know whether you can apply the concept.
❌ Mistake 2: Saying “I will test everything”
Real projects have limited time.
Show prioritization and risk-based thinking.
❌ Mistake 3: Blaming developers
QA and development are working toward the same goal: a quality product.
❌ Mistake 4: Memorizing answers
Interviewers often change the scenario.
Understand the logic behind the answer.
❌ Mistake 5: Ignoring business impact
A good QA Engineer understands that not every defect has the same business risk.
🧠 How to Make Your Answers Sound More Experienced
Instead of saying:
“I will test the login page.”
Say:
“I would first understand the login requirements and identify positive, negative, boundary, security and usability scenarios.”
Instead of:
“I will report the bug.”
Say:
“I would reproduce the issue, assess its impact, raise it with appropriate severity and priority, and provide enough evidence for the developer to investigate.”
Instead of:
“I will do regression testing.”
Say:
“I would identify the impacted areas and execute regression testing based on the change and associated risk.”
These small changes can make your answers sound much more practical and mature.

🏆 Final Takeaway
A successful Manual Testing interview is not a memory test.
The interviewer is trying to understand:
Can you think like a tester?
Can you:
- Ask the right questions?
- Identify risks?
- Think beyond positive scenarios?
- Prioritize under pressure?
- Communicate defects clearly?
- Handle disagreements professionally?
- Understand business impact?
- Make sensible testing decisions?
That’s what separates a candidate who knows testing terminology from a candidate who can actually work as a QA Engineer.
Don’t memorize 50 answers. Learn the thinking pattern behind them.
When you understand the why, you can answer even the questions you have never seen before.
If you want to review standard software testing terminology, you can also refer to the official ISTQB Glossary.
