Tell about your key responsibilities and participation in previous projects.

In my previous projects, my key responsibilities included:

• Developing and maintaining automated tests for web applications and APIs.
• Analyzing requirements and preparing test cases.
• Conducting functional, regression, and integration testing.
• Using automation tools such as Selenium WebDriver, JUnit/TestNG, Postman.
• Setting up CI/CD pipelines to run tests automatically.
• Collaborating with the development team to identify and reproduce bugs.

For example, in one project, I created a set of automated tests for REST API, which reduced regression testing time from several days to a few hours.
