The interview lasted one hour and was highly professional.

Key discussion points included:

1. About the project and testing framework.
2. Questions on OOPs concepts, with specific examples requested for interfaces, which were not clearly understood over the phone call.
3. Very basic questions on Java regarding heap memory and garbage collection.
4. Experience with Linux/Unix machines.
5. Exception hierarchy.
6. Real-time exceptions using Selenium WebDriver.
7. Types of locators in Selenium and about XPath.
8. final and finally blocks.
9. findElement and findElements.

Working experience on Linux or Unix. I said no to HR during screening, but I was still asked and disqualified based on that.
