There were 5 rounds.

The first was the online aptitude test, which I cleared.

4. Is Selenium dependent on browser versions?

5. Write a program to determine if a string is a palindrome.

6. After writing the program, he asked me to optimize the code further, which I did.

7. He asked me about Selenium Grid.

Round 2

1. Write a program (WAP) to reverse a string. Optimize the code further and implement it in another manner.

2. How do you make Selenium code compatible for different browsers?

3. Write code to run a test case on three different browsers, one after the other.

4. What is virtual memory and paging?

5. How is task scheduling done by the CPU?

6. File Systems and I/O Streams.
