As an SDET (Software Development Engineer in Test), you play a crucial role in the software development process, ensuring that the software meets the expected quality standards. Whether you are a seasoned SDET or just starting out, preparing for an SDET interview can be overwhelming. In this short article, we will provide you with a list of the top SDET Interview Questions and their Answers to help you prepare for your next interview.
1- What is an SDET, and what do they do?
An SDET is a software development engineer in test. They are responsible for ensuring that software meets the expected quality standards by designing, developing, and executing automated test scripts, analyzing test results, and working with the development team to identify and fix defects.
2- What is the difference between an SDET and a QA engineer?
An SDET is a developer with a strong testing background who can create and maintain automation frameworks and tools. A QA engineer, on the other hand, focuses more on manual testing and identifying bugs and defects.

5- What are the different types of testing?
There are several types of testing, including functional testing, non-functional testing, performance testing, load testing, security testing, and more.
6- What is regression testing?
Regression testing is the process of testing changes to software to ensure that existing functionality is not affected.
7- What is the difference between functional and non-functional testing?
Functional testing focuses on the functionality of the software, while non-functional testing focuses on the performance, reliability, and security of the software.
