What should I focus on for a QA Engineer interview?
Which topics matter more for this role?
Test planning, automation and manual test design stand out. These topics appeared more often in QA Engineer interviews than across all interviews in the sample. The questions leaned toward junior and mid-level knowledge.
Start with checks that cover both testing choices and how you carry them out:
- Can you turn requirements into a test plan and explain the risks?
- Can you design tests for a feature, not just name testing types?
- Can you describe the parts of an automation framework and how they fit together?
- Can you explain what a bug report needs so someone can reproduce and fix the issue?
Which common questions should I check first?
The most asked questions each appeared in 8 of 165 interviews. Check whether you can answer them directly:
- What is the difference between
PUTandPATCH, and when would you use each? - What advantages does Playwright have over Selenium?
- How do you use AI tools in your testing work?
Other common questions covered testing types, API testing, automation choices and the Page Object Model. Can you say when you would use each testing type? For an API, can you describe your test cases and what you would check in the response? Can you explain how you use the Page Object Model and its advantages?
What did real answers leave out?
Explain your choices, not just your list of tests. Reviewed answers about choosing automation missed how feature stability and frequency of change affect when a test is ready to automate. Under a tight deadline, can you explain how those factors shape what you automate and what you test manually?
Reviewed login-testing answers missed test order based on user impact and security risk. Can you put your login checks in order and explain why particular cases should come first?
Do I need to write code?
Coding tasks appeared in 34 of 165 interviews. Check whether you can write the code, rather than only describe an approach:
- Check whether a string is a palindrome in Java.
- Read test data from an Excel or CSV file in Python.
- Reverse a string.
- Find the second-largest element in an array.
- Check in Python whether an object is an instance of a particular type, such as
Apple.
Programming questions also covered object-oriented concepts, data structures, concurrency and file handling.

What is the difference between PUT and PATCH, and when would you use each?
Asked in 8 of 165 interviews · last asked Oct 22 · Concept · Junior
Show answer
PUT creates or replaces a resource at a known URL. PATCH applies a set of changes to a resource. I use PUT when sending the full replacement state, and PATCH when changing only part of it.
- PUT is idempotent: repeating the same request has the same intended effect as sending it once.
- PATCH is not always idempotent; setting a value differs from incrementing it.
- Check the API contract for required fields, omitted fields, and supported patch formats.
What the interviewer checks: The interviewer checks whether you understand replacement, partial updates, and the effects of retrying requests.
Other ways it was asked
- “Can you explain the difference between PUT and PATCH requests?”
- “What is the difference between PUT and PATCH?”
- “What is the difference between the PUT and PATCH methods?”
What are the advantages of Playwright over Selenium?
Asked in 8 of 165 interviews · last asked Oct 22 · Concept · Mid-level
Show answer
Playwright offers automatic waits for actions, easy network mocking, and built-in tracing for debugging. Its lightweight browser contexts make isolated tests quick to set up. These features can reduce test code and maintenance compared with Selenium, but do not guarantee faster tests. Selenium supports more programming languages and is better suited to testing actual Safari.
- Automatic action checks reduce manual waits, but some application states still need explicit checks.
- Browser contexts isolate cookies and storage without starting a separate browser for every test.
- Playwright Test provides parallel execution and retries for JavaScript and TypeScript tests.
- Playwright supports Chromium, Firefox, and WebKit; WebKit testing is not the same as testing actual Safari.
What the interviewer checks: The interviewer checks whether you understand practical benefits and limits, rather than claiming one tool is always better.
Other ways it was asked
- “What are the advantages of Playwright compared with Selenium or Cypress?”
- “Why might Playwright be more convenient and faster than Selenium?”
- “What is the difference between Selenium and Playwright?”
How do you use AI tools in your testing work?
Asked in 8 of 165 interviews · last asked Oct 22 · Tooling
Show answer
I use AI tools to suggest test cases, draft test scripts, and help explain errors. I check the suggestions against requirements and run any generated tests before using them. I use approved tools and avoid sharing private data. AI saves time, but I stay responsible for the results.
- Use AI for test ideas, script drafts, and error analysis.
- Check generated tests for correct steps, assertions, and expected results.
- Follow company rules for sharing code and data.
- Use AI to support judgment, not replace it.
What the interviewer checks: The interviewer is checking whether you use AI practically while protecting data and checking its output.
Other ways it was asked
- “Do you use any AI tools in your day-to-day work, and what kinds of tasks do you use them for?”
- “How do you use AI in your daily work?”
- “How do you use AI to make your work faster and better?”
What are the different types of software testing, and when would you use them?
Asked in 7 of 165 interviews · last asked Oct 19 · Concept · Junior
Show answer
I use unit tests to check small pieces of code in isolation. Integration tests check whether connected parts work together. System tests check the whole application against its requirements. Acceptance tests check whether it meets business needs and is ready for users.
- Functional testing checks required behavior; non-functional testing checks qualities such as performance, security, and usability.
- Smoke tests quickly check critical functions before deeper testing.
- Regression testing checks whether changes broke existing behavior; retesting checks whether a specific bug was fixed.
- Exploratory testing uses learning and investigation to find issues that planned tests may miss.
What the interviewer checks: The interviewer checks whether you can distinguish test levels and purposes and choose tests for different situations.

- “How would you explain the different types of software testing, with examples?”
- “What are the different types of software tests?”
How do you test an API, and what test cases and validations would you include?
Asked in 7 of 165 interviews · last asked Sep 17 · Concept · Mid-level
Show answer
I test an API against its documented contract and business rules, using an API client and automated tests. I cover valid requests, invalid inputs, boundary values, and access control. I check status codes, headers, response data, and database changes, then test response times and failures under expected load.
- Check response structure, field types, values, and error messages, not just status codes.
- Test missing fields, wrong types, boundary values, and missing or expired credentials.
- Verify users cannot access another user's data or perform actions without permission.
- Check saved data and side effects; test pagination, retries, and duplicate requests where relevant.
What the interviewer checks: The interviewer checks whether you can build useful test coverage and verify behavior beyond a successful response.
Other ways it was asked
- “How do you test an API, and what specifically do you verify?”
- “What aspects of an API would you test?”
- “What validations do you perform for an API?”
How do you decide what to automate and what to test manually, especially under tight deadlines?
Asked in 7 of 165 interviews · last asked Oct 18 · Concept · Senior
Show answer
I automate stable, repeatable tests that run often and catch important failures. I use manual testing for exploration, usability, and features that change too often for automation to pay off. Under tight deadlines, I test the highest risks first and automate only where it saves time. I stop maintaining an automated test when its cost outweighs its value.
- Prioritize critical user flows and areas where failures would cause the most harm.
- Consider how often tests run, setup effort, and maintenance cost.
- Frequent changes to expected behavior can make automation costly; reassess when the feature stabilizes.
- Keep manual testing for exploration and judgments that need human attention.
What the interviewer checks: The interviewer checks whether you balance risk, time, feature stability, and maintenance cost rather than automate everything.
Common mistake (in 3 of 5 reviewed answers): Many answers forget that feature stability and how often behavior changes help decide when a test is ready for automation.
Other ways it was asked
- “How do you decide what to automate and what to test manually? What is worth automating?”
- “How do you decide what to automate, what not to automate, and when to stop automating a test?”
- “How do you decide what to automate versus what you keep manual?”
What are the key components of a test automation framework, and how are they structured?
Asked in 6 of 165 interviews · last asked Oct 8 · Design · Mid-level
Show answer
I structure a test automation framework in layers: tests, reusable actions, and shared tools. Tests describe scenarios and check results. Page objects or API clients handle interactions, while fixtures manage setup and cleanup. Separate modules hold test data and configuration; a test runner executes tests and produces reports and failure logs.
- Keep test logic separate from UI selectors, API calls, and shared utilities.
- Use fixtures for setup and cleanup so tests can run independently.
- Keep environment settings and test data separate from test code; store secrets securely.
- Connect the test runner to CI and save reports, logs, and screenshots when useful.
What the interviewer checks: The interviewer checks whether you can organize reliable tests that are easy to maintain, debug, and run automatically.
Other ways it was asked
- “How would you create a new test automation framework?”
- “Can you describe the structure and key components of an automation testing framework?”
- “How is a test automation framework typically structured?”
What is the Page Object Model, how do you use it, and what are its advantages?
Asked in 6 of 165 interviews · last asked Oct 12 · Concept · Mid-level
Show answer
The Page Object Model is a test automation pattern that keeps page details separate from test steps. I put each page’s element locators and actions in a class, then call those actions from tests. It reduces repeated code, makes tests easier to read, and lets me update locators in one place when the UI changes.
- Use it in UI automation, especially when several tests use the same pages.
- Page objects hold locators and expose actions such as login or search.
- Tests control the scenario and usually keep assertions about expected results.
- Reusable page components can represent shared parts, such as navigation menus.
What the interviewer checks: The interviewer is checking whether you can separate UI details from test logic to make tests easier to maintain.
Other ways it was asked
- “What is the Page Object Model, and when would you use it?”
- “What is the Page Object Model, and how have you used it in test automation?”
- “What is the Page Object Model, and how do you use it in test automation?”
What is the difference between verification and validation?
Asked in 5 of 165 interviews · last asked Oct 1 · Concept · Junior
Show answer
Verification checks whether the software meets its specified requirements. Validation checks whether it meets user needs and works for its intended use. Software can pass verification but fail validation if the requirements do not reflect what users actually need.
- Verification asks: Are we building the product right?
- Validation asks: Are we building the right product?
- Verification can include reviews and tests; validation often includes acceptance testing with realistic user tasks.
What the interviewer checks: The interviewer checks whether you understand the difference between meeting written requirements and meeting real user needs.
Other ways it was asked
- “What is the difference between validation and verification?”
- “What do you mean by verification and validation?”
What information should a bug report include to help reproduce and fix the issue?
Asked in 5 of 165 interviews · last asked Oct 12 · Concept · Junior
Show answer
A bug report should include a clear title, environment and build version, setup conditions, and exact steps to reproduce the issue. It should state the expected and actual results, how often the issue happens, and its impact. I would add severity and useful evidence, such as screenshots, logs, or error messages, without exposing sensitive data.
- Include required test data, account permissions, and setup conditions.
- Write numbered steps that another person can follow.
- Separate expected behavior from actual behavior.
- Severity describes impact; priority describes how urgently the bug should be fixed.
What the interviewer checks: The interviewer is checking whether you can document a bug clearly enough for someone else to reproduce and investigate it.
Other ways it was asked
- “What information should a well-written defect report include?”
- “What makes a good bug report?”
- “What fields should a good defect report include to help reproduce and fix the issue?”
How would you test a login page, including functionality, security, and edge cases?
Asked in 5 of 165 interviews · last asked Oct 12 · Scenario · Junior
Show answer
I would prioritize valid login and attempts to access protected pages without logging in, because access failures and unauthorized access have high impact. Next, I would test wrong passwords, password reset, and MFA if supported. I would check session handling and attack protection. Then I would cover input limits, network failures, and browser compatibility.
- Check valid and invalid credentials, disabled accounts, and clear errors that do not reveal whether an account exists.
- Check HTTPS, password exposure, injection protection, and rate limits against repeated login attempts.
- Verify logout and session expiry block further access, and login creates a new session identifier.
- Test empty fields, long inputs, repeated clicks, and network timeouts without changing the intended password.
What the interviewer checks: The interviewer wants to see risk-based priorities and coverage of normal login, security controls, and failure cases.
Common mistake (in 3 of 8 reviewed answers): Many answers forget that test order should follow user impact and security risk, so explain why critical cases should come first.
Other ways it was asked
- “How would you approach testing a new login feature to ensure it is both secure and functional?”
- “Could you walk me through how you would test a new login feature to make sure it works correctly and keeps user data safe?”
- “Which edge cases would you prioritize when testing a login feature?”
What is CI/CD, and how does it support software testing?
Asked in 5 of 165 interviews · last asked Oct 13 · Concept · Junior
Show answer
CI/CD means continuous integration and continuous delivery or deployment. CI builds and tests code changes often, so teams find problems early. Continuous delivery keeps tested changes ready for release; continuous deployment releases them automatically when checks pass. Tests in the pipeline give fast feedback and can block changes that fail checks.
- Pipelines can run unit, integration, and end-to-end tests automatically.
- Fast tests usually run first; slower tests run later.
- Continuous delivery may require release approval; continuous deployment does not require manual approval.
- Automated checks support testing but do not replace exploratory testing.
What the interviewer checks: The interviewer checks whether you understand CI/CD, its release options, and how automated tests help control software quality.
Other ways it was asked
- “What is CI/CD?”
- “What do you know about CI/CD?”
- “What is CI/CD, and how is it used in software testing?”
What is white-box testing, and how does it differ from black-box testing?
Asked in 4 of 165 interviews · last asked Aug 25 · Concept · Junior
Show answer
White-box testing uses knowledge of the code to design tests for internal logic, such as conditions and branches. Black-box testing checks inputs and outputs against requirements without using the internal code to design tests. Both help find defects, but they test the system from different views.
- White-box tests use code structure to choose test cases.
- Black-box tests use requirements and expected behavior to choose test cases.
- White-box coverage can measure statements or branches exercised by tests.
- High code coverage does not prove the software meets requirements.
What the interviewer checks: The interviewer checks whether you understand how code knowledge affects test design and why both approaches are useful.
Other ways it was asked
- “Can you compare black-box testing and white-box testing?”
- “Can you compare black-box and white-box testing?”
- “What is the difference between black-box and white-box testing?”
What is the difference between smoke, sanity, and regression testing?
Asked in 4 of 165 interviews · last asked Oct 24 · Concept · Junior
Show answer
Smoke testing checks whether the main features work well enough to continue testing a build. Sanity testing usually checks a specific change and closely related features. Regression testing checks whether changes broke existing behavior. Teams may use these terms differently, especially sanity testing.
- Smoke tests cover key functions broadly, without deep testing.
- Sanity tests are usually narrow and focused on a recent change.
- Regression tests cover existing behavior that a change could affect.
- These test sets can overlap; regression testing does not always mean running every test.
What the interviewer checks: The interviewer is checking whether you can choose the right test scope for a build or change.
Other ways it was asked
- “What’s the difference between smoke testing and sanity testing?”
- “What is the difference between smoke testing and sanity testing?”
- “What is the difference between regression testing and sanity testing?”
What is a test case?
Asked in 4 of 165 interviews · last asked Oct 1 · Concept · Junior
Show answer
A test case is a set of conditions, inputs, steps, and expected results used to check a specific software behavior. It usually includes an ID, a description, setup needs, test data, steps, and expected results. When I run it, I record the actual result and whether it passed or failed.
- A test case checks a specific behavior or requirement.
- Setup needs and test data make the test repeatable.
- Expected results define what correct behavior looks like.
- Actual results and pass or fail status are recorded during execution.
What the interviewer checks: The interviewer checks whether you can define a test case and explain what makes it clear and repeatable.
Other ways it was asked
- “Can you define a test case?”
- “What is a test case, and what are its key components?”
What is the difference between severity and priority?
Asked in 4 of 165 interviews · last asked Oct 12 · Concept · Junior
Show answer
Severity is how much a bug affects the system or users. Priority is how soon the bug should be fixed. A severe bug can have low priority if it affects a rarely used feature with a workaround. A small typo can have high priority if it appears on the main page before a launch.
- Severity describes the bug’s impact.
- Priority reflects business needs, urgency, and release plans.
- High severity does not always mean high priority.
What the interviewer checks: The interviewer is checking whether you can separate a bug’s impact from the urgency of fixing it.
Other ways it was asked
- “What is the difference between severity and priority in software testing?”
At what point do you decide to stop troubleshooting a technical issue on your own and reach out for help?
Asked in 4 of 165 interviews · last asked Sep 3 · Scenario
Show answer
I ask for help when I stop making progress, reach an agreed time limit, or risk delaying important work. I ask sooner if the issue affects users, security, or data. I share what happened, what I tried, and the evidence so the other person can help without repeating my work.
- Set a troubleshooting time limit based on urgency and impact.
- Ask sooner if users, security, or data are at risk.
- Share steps to reproduce, relevant logs, and what you have ruled out.
- Ask someone with the right knowledge or access.
What the interviewer checks: The interviewer is checking whether you balance independent problem-solving with timely teamwork and clear communication.
Other ways it was asked
- “When do you decide to stop troubleshooting alone and ask for help?”
- “At what point do you stop trying to fix an issue on your own and reach out to someone for assistance?”
Can you explain boundary value analysis with a suitable example?
Asked in 4 of 165 interviews · last asked Oct 24 · Concept · Junior
Show answer
Boundary value analysis is a test design method that checks values at and just outside the limits of an input range. It helps find errors in how limits are handled. For an age field that accepts whole numbers from 18 to 60, inclusive, I would test 17, 18, 19, 59, 60, and 61.
- Test each limit and the nearest values on both sides.
- Confirm whether each limit is included in the valid range.
- Equivalence partitioning groups inputs with similar expected behavior; boundary value analysis focuses on the edges.
CodeValid age range: whole numbers from 18 to 60, inclusive. 17: reject 18, 19: accept 59, 60: accept 61: rejectWhat the interviewer checks: The interviewer is checking whether you can find input limits and choose tests that catch errors at those limits.
Other ways it was asked
- “What is boundary value analysis?”
- “Can you explain boundary value analysis?”
- “Can you give me an example of boundary value analysis and equivalence partitioning?”
What is exploratory testing?
Asked in 4 of 165 interviews · last asked Oct 13 · Concept · Junior
Show answer
Exploratory testing means learning about a product, designing tests, and running them at the same time. I use what I find to choose what to test next, rather than following only fixed test steps. It is useful for new features, unclear requirements, and finding issues that scripted tests may miss.
- Testing decisions change as you learn about the product.
- A clear goal and a time limit help keep testing focused.
- Record what you tested, what you found, and any unanswered questions.
- It complements scripted testing; it is not random clicking.
What the interviewer checks: The interviewer is checking whether you understand how to explore a product with purpose and adapt your tests.
Other ways it was asked
- “What does the term exploratory testing mean?”
- “What is exploratory testing, and when would you use it?”
How would you structure a CI/CD pipeline to run automated tests?
Asked in 4 of 165 interviews · last asked Sep 18 · Behavioral · Mid-level
Show answer
I would run fast checks and unit tests on each pull request, then build the app and run integration tests. After deploying to a test environment, I would run key end-to-end tests. Failed required tests would block release, with reports available for debugging. After production deployment, I would run smoke tests and roll back if needed.
- Run fast tests first so developers get quick feedback.
- Use isolated test data and a test environment that closely matches production.
- Publish test results and failure logs; investigate flaky tests rather than hiding failures with retries.
- Run independent tests in parallel, and schedule slower, broader suites when needed.
What the interviewer checks: The interviewer checks whether you can arrange reliable tests to give fast feedback and control release risk.
Other ways it was asked
- “What stages and activities are typically part of a test automation pipeline?”
- “Can you describe the workflow of a test automation pipeline?”
- “How do you integrate testing into a CI/CD process, which tools do you use, and how does the process work?”
Software testing fundamentals interview questions
Questions cover testing principles, test types and levels, development and testing life cycles, verification, validation and the testing pyramid. 75 questions.
What is unit testing?
Asked in 3 of 165 interviews · last asked Oct 2 · Concept · Junior
Show answer
Unit testing checks a small piece of code, such as a function or method, on its own. It checks whether the code gives the expected result for normal inputs, edge cases, and errors. Developers usually write these tests and run them automatically.
- Tests focus on one small unit, not the whole application.
- External dependencies may be replaced with test doubles, such as stubs or mocks.
- Unit tests should be fast, repeatable, and independent of other tests.
- They help catch bugs early but do not replace integration or system tests.
What the interviewer checks: The interviewer is checking whether you understand the scope and purpose of unit tests.

How this list is made
Every question here was asked by a real interviewer in a real job interview that a candidate ran MeetAssist in. After the call, the interviewer's questions are pulled from the transcript. Practice sessions, tests, exams and anything that was not a job interview are dropped.
Questions are rewritten so they make sense on their own: names of people, employers and clients are removed, and speech-to-text mistakes are fixed. Small talk, logistics and questions about one candidate's own résumé are left out. Rephrasings of the same question are merged, and the count is the number of different interviews it came up in.
The interviews come from candidates who use MeetAssist, so they lean towards software, data and AI roles: the shares describe these interviews, not every QA Engineer interview. Answers to the most asked questions are written and checked by an editor; a "common mistake" is shown only when reviews of real answers in these interviews show it, with the count.
165 interviews, 66 candidates, Jan 2026 to Oct 2026. Updated every month with new interviews.
