Whereas one debugging question and 3 codings question easy to moderate level. I have to remember one question was the implementation of HashMap in java.
  In this test, the total participate candidate was approx 450 after this round total of only 12 candidates shortlisted including me.

He asked a coding question that was the Next greater element of the array.https://www.geeksforgeeks.org/next-greater-element/
I told the algorithm about this problem and after that, he told me that write a code in an online editor
I wrote and run successfully. He is very impressed with me.

After this round, only one candidate out of 12 was selected for the next round that was I.

Firstly he asked me which programming language you know and give a rating for that. I told java and 8 with the rating.
After that he started with a coding question there was a total of two coding questions asked.

1. Find the median from the linked list in an optimal way.
2. Check a tree is BST or not.
   I told the algorithm for both in an optimal way and wrote code in the online editor and run.

After that, he jumped on collection in java and asked more deeply question from there.
He basically asked array list and vector in java how it is implemented and how increased there size
Automatically. (What is a dynamic array in java). I told him all the answers to his question.

After that, he jumped on the oops concept in java. And asked what is runtime polymorphism in java and how can we implement? He told write code for runtime polymorphism. And then he asked for data abstraction in java. And more OOPs concept.

After that he jumped on DBMS he creates two tables and asked to join SQL query and more SQL query such as
