Starting a career in QA? Interviews can be easy if you prepare well. Here are the most common questions and answers you’ll likely face in a QA interview. All explained in a simple way for anyone to understand.
1. What is QA (Quality Assurance)?
Answer:
QA is the process of checking if the software is made correctly and meets the required quality. It helps prevent bugs and problems.
2. What is Software Testing?
Answer:
Testing is the process of finding mistakes (bugs) in software and making sure it works properly.
3. What is the difference between QA and Testing?
Answer:
QA is about improving the process to avoid bugs.
Testing is about finding bugs in the software.
4. What is a Bug?
Answer:
A bug is a mistake or problem in the software that makes it work in the wrong way.
5. What is a Test Case?
Answer:
A test case is a set of steps written to check if a part of the software works as expected.
6. What is Manual Testing?
Answer:
Manual testing is when a person checks the software without using any tools or scripts.
7. What is Automation Testing?
Answer:
Automation testing uses tools or scripts to test software automatically.
8. What is SDLC?
Answer:
SDLC (Software Development Life Cycle) is the step-by-step process of making software, like planning, building, testing, and releasing.
9. What is STLC?
Answer:
STLC (Software Testing Life Cycle) is the process followed to test the software, including planning, designing test cases, testing, and reporting bugs.
10. What is Regression Testing?
Answer:
It means testing old features again after changes to make sure nothing is broken.
11. What is Smoke Testing?
Answer:
A quick check to see if the main functions of the software are working or not.
12. What is Sanity Testing?
Answer:
It is a basic test to make sure new changes or bug fixes are working properly.
13. What is the difference between Smoke and Sanity Testing?
Answer:
- Smoke testing checks basic functions after a new build.
- Sanity testing checks small changes or bug fixes.
14. What is Functional Testing?
Answer:
It checks if the software features work as expected.
15. What is Non-Functional Testing?
Answer:
It checks how well the software performs, like speed, load time, and security.
16. What is a Test Plan?
Answer:
A test plan is a document that explains how testing will be done—what to test, how to test, and who will test.
17. What is a Test Scenario?
Answer:
A test scenario is a high-level idea of what to test, without step-by-step details.
18. What is the difference between a Test Case and a Test Scenario?
Answer:
- Test Case = Detailed steps to test something
- Test Scenario = General idea of what to test
19. What tools are used in QA?
Answer:
Some common tools are:
- JIRA – for tracking bugs
- Selenium – for automation testing
- Postman – for API testing
20. Why do you want to work in QA?
Answer:
Because I like finding and solving problems. I want to make sure software is bug-free and users are happy.
🎯 Final Tip for Freshers:
Interviewers care more about how clearly you explain things than using big words. Stay calm, be honest, and show your eagerness to learn.
