QA Engineers are in high demand due to the critical role they play in ensuring the quality, reliability, and performance of software products. As software development cycles become faster with methodologies like Agile and DevOps, the need for continuous testing and quality assurance has grown significantly. Companies are increasingly dependent on complex software systems, and any bugs or defects can lead to substantial financial losses, damage to brand reputation, and customer dissatisfaction. QA Engineers help mitigate these risks by identifying issues early in the development process, ensuring that the software meets both functional and non-functional requirements.

Top 5 Technical Interview Questions Asked to QA Engineer
Answer: Functional Testing focuses on verifying that the software functions according to the specified requirements. This includes testing user interfaces, APIs, databases, security, client/server applications, and functionality of the software. Non-Functional Testing, on the other hand, refers to aspects such as performance, usability, reliability, and scalability. It ensures that the software performs well under specific conditions, such as heavy load, and meets other quality criteria beyond basic functionality.
Answer: Test Automation involves using automated tools to execute pre-scripted tests on a software application before it is released into production. Automation is particularly useful in regression testing, performance testing, and repeated test cases, where manual testing would be time-consuming and prone to human error. It should be used when the same test scenarios need to be run frequently and when dealing with large datasets that would be impractical to test manually.
Answer: A bug is an error found in the code that can cause the software to behave unexpectedly. A defect is a variance between the expected and actual result in the software, which may be caused by a bug in the code. A failure occurs when the software fails to perform a required function, often due to the presence of defects or bugs in the code. Essentially, a bug causes a defect, and when that defect leads to an incorrect result during execution, it is considered a failure.
Answer: Testing a new feature involves several steps:
- Understand Requirements: Review the requirements and specifications of the new feature to understand what it should do.
- Design Test Cases: Create detailed test cases that cover all possible scenarios, including edge cases and boundary conditions.
- Environment Setup: Ensure that the testing environment is set up correctly with all necessary configurations.
- Execute Tests: Perform both manual and automated tests to verify that the new feature works as expected.
- Regression Testing: Run regression tests to ensure that the new feature has not introduced any new bugs or issues in the existing functionality.
- Report Issues: Log any defects found during testing and collaborate with developers to resolve them.
- Retest: After fixes, retest the feature to ensure all issues are resolved and the feature meets the requirements.
Answer: Software testing can be broadly categorized into several types:
- Unit Testing: Tests individual units or components of the software.
- Integration Testing: Tests the interaction between integrated units or components.
- System Testing: Tests the complete, integrated system to ensure it meets the specified requirements.
- Acceptance Testing: Verifies that the system meets the business requirements and is ready for production.
- Performance Testing: Assesses the system’s performance under various conditions, such as load and stress.
- Security Testing: Ensures that the system is secure from threats and vulnerabilities.
- Usability Testing: Evaluates the user interface and overall user experience.
