Basic QA Interview Questions

Here is a list of basic Quality Assurance interview questions and answers: 

  1. What is Quality Assurance (QA), and why is it important?

Quality Assurance (QA) is a process that focuses on maintaining the quality of software throughout its development lifecycle. It involves identifying defects, following best practices, and preventing errors before they reach users. QA is important because it helps deliver reliable software, reduces costs associated with fixing defects later, and improves user satisfaction.

  1. How is QA different from Quality Control (QC) and Testing?

QA focuses on improving processes to prevent defects. QC checks the final product to identify and fix defects. Testing, a part of QC, involves executing test cases to detect issues in the software. In short, QA improves processes, QC checks the final output, and testing detects issues in the product.

  1. What are the different types of software testing?

This is one of the most common QA interview questions.

Software testing includes:

  • Functional testing: Checks if the software meets requirements.
  • Non-functional testing: Evaluates performance, security, and usability.
  • Manual testing: Performed without automation tools.
  • Automation testing: Uses tools like Selenium or JUnit.
  • Regression testing: Ensures new changes don’t break existing functionality.
  • Unit testing: Tests individual components or modules.
  • Integration testing: Verifies if modules work together.
  1. What is the Software Development Life Cycle (SDLC), and where does QA fit in?

SDLC is a structured process for developing software. It consists of planning, design, development, testing, deployment, and maintenance. QA is involved in all phases to prevent defects early and maintain quality throughout the process.

QA Fresher Interview Questions

These Quality Assurance interview questions and answers are for freshers:

  1. What is the difference between functional and non-functional testing?

Functional testing checks if the software performs expected actions based on requirements. Non-functional testing evaluates aspects like speed, security, and usability, which impact user experience but aren’t tied to specific functions.

  1. What do you understand by black box and white box testing?

Black box testing focuses on software behavior without knowing its internal code, whereas white box testing requires knowledge of the internal structure to test code logic and data flow.

  1. What is regression testing, and when should it be performed?

If you are looking for Quality Assurance important questions – do not skip this one. 

Regression testing is conducted after code changes to confirm that existing functionality still works correctly. It should be performed after bug fixes, enhancements, or system upgrades.
