Takeaway: A tight, impact-focused intro sets a confident tone.

What are the top general QA interview questions I should memorize?

• Tell me about your QA experience.

• What is your testing process from requirements to release?

• Describe a time you found a critical bug. How did you handle it?

• How do you prioritize test cases?

Answer: Employers frequently ask: your testing process, biggest bug you found, how you handle missed defects, and why QA is important.
Common examples:
For each, use structure (STAR/CAR): Situation, Task, Action, Result or Context, Action, Result. Quantify outcomes where possible.
Takeaway: Prepare 4–6 concise stories demonstrating process and impact.

How do I answer behavioral questions in a QA interview?

Answer: Use STAR: outline the Situation, Task, Action, and Result to show context and measurable outcomes.
Example prompt: “Tell me about a time you disagreed with a developer.” Answer: Briefly set the scenario, explain your responsibility, describe how you discussed evidence (logs, steps to reproduce), propose a compromise (retest + fix), and provide the outcome (faster resolution, improved test coverage). Emphasize collaboration, learning, and prevention steps.
Takeaway: Behavioral answers should show teamwork, ownership, and continuous improvement.

Which technical topics should I master for QA interviews?

• STLC vs SDLC

• Types: unit, integration, system, regression, smoke, sanity, UAT, performance, security

Takeaway: Show the rationale behind tool choices and how automation improved quality.

How do I explain regression testing or test coverage in an interview?

Answer: Regression testing ensures new changes don’t break existing functionality; test coverage measures how much of the app or code is exercised by tests.
Explain strategies: risk-based selection of regression tests, tagging tests, running smoke/regression suites in CI, and using coverage tools for unit tests. Distinguish code coverage (lines/branches) from requirements coverage (feature/test-case mapping). Provide examples where improving coverage prevented production bugs.
Takeaway: Demonstrate pragmatic, risk-based approaches to coverage and regression.

What technical question could I get about API testing and how should I answer?

Answer: Expect questions on HTTP methods, status codes, authentication, and tools like Postman or RestAssured.
Example Q: “How do you validate an API?” Answer: Check status codes, headers, payload structure, schema validation (JSON Schema), edge cases, idempotency, performance under load, and security (auth tokens). Give an example where you created automated API tests in a CI pipeline and caught regression after a backend change.
Takeaway: Combine protocol basics with automation and real-world examples.

How do I handle questions about SQL and data verification?

Answer: Demonstrate basic query skills and how you validate data integrity during tests.
Prepare to explain SELECT, JOINs, aggregations, and how you use SQL to verify test results or seed data. Example: “I use queries to confirm DB changes after a transaction and to create test fixtures for automation.” Provide a short example query you’ve used to validate a bug fix.
Takeaway: Show ability to use DB checks to verify end-to-end functionality.

What are good answers to “How do you prioritize test cases?”

Answer: Use risk-based prioritization: customer impact, business criticality, change frequency, and past defect history.
Process: map requirement criticality → identify high-risk features → prioritize smoke and core flows → automate regression for frequently changed areas. Use test metrics like test execution time and flakiness to refine the suite. Provide a concise example where prioritization prevented a major issue.
Takeaway: Prioritization should align testing effort with business risk.

How do I answer “How do you write a bug report?”

Answer: A clear bug report includes title, steps to reproduce, actual vs expected results, environment, logs/screenshots, severity/priority, and reproduction rate.
Share a template: summary, environment (OS/browser/version), preconditions, steps, observed result, expected result, attachments, and suggested area/owner. Emphasize concise, reproducible steps and why reproducibility matters for debugging speed.
Takeaway: Clear bug reports speed up fixes and build credibility.

What are the most common situational QA interview questions and sample approaches?

• Missed release: communicate status, triage fixes, apply hotfix policy, postmortem

• Production bug: gather facts, rollback if needed, create mitigation plan, inform stakeholders
