First Round: The interviewer asked about the current company and my contributions. Then, there was a simple live coding exercise of merging two sorted array lists into one sorted array list, and also a few core Java questions.

Second Round: This technical round involved coding questions about rotating a string, ordering an array with odd numbers on the left and even numbers on the right, and Java 8 features. There were also questions on multithreading and binary trees. The interviewer was highly patient. They provided hints during the interview to optimize code and gave feedback on performance.
