QA Interview Questions and Answers – for Software QA tester and QA analyst

QA software tester plans & conducts various test processes to new developed software in order to verify that the software programs functions according to the initial requirements.

The compatibility, functionality and the quality of the product is tested according to pre established quality standards and guidelines.

The difference between QA analysts (QA engineers) and products/software QA testers is that the quality assurance analysts focus on improving and minimizing defects and preventing mistakes from accruing in the first place, while QA testers perform Quality Control tests in order to find bugs and diagnose errors per pre/post product release.

This article provides wide ranging of interview questions for QA positions such as – QA engineers, Quality Assurance analysts and SQA testers and suggests answers for the same.
QA testing interview questions and answers – software QA interview questions with answers

The following questions are good for QA engineers, quality assurance QA analysts and SQA, software QA testers’ professionals:

• What is the meaning of traceability matrix?
Answer – Tractability matrix is used to cross check the test scripts per the requirement of the test cases.


• What is the difference between verification and validation?
Answer – Verification is based on verifying the functionality of a new system while validation is based on testing scenarios and test cases of a new system.

• Describe the role of software QA in terms of the test plan – scope of work, monitoring reliability and project implementation.
Answer – You should explain how you determine the timing for system testing, what to test and when do you finalize the testing?

• Describe test strategy – What are the steps you generally take to test any software? What is the first test in software testing process?
Answer – Unit testing is the first test that is usually done by the developers. You have to explain the methods you use for preparing test data per the test cases requirements that you have defined.
