It was an online interview for campus placement.

First, there were two questions in the coding round. Both were easy.

The interview process was smooth and consisted of three rounds.

• Round 1 was about 1 hour long.
• I was called for Round 2 after 15 minutes. This round was also around 1.5 hours long.
• I was called for Round 3 almost immediately after the second round. This round was about 40-50 minutes long.

There were 3 rounds of interviews.

In the first round, there were 2 questions, and I had to explain and code both. The first question was based on merging intervals. The second question involved a binary tree where I had to find the size of a subtree in which all nodes have a value of 0.

In round 2, there were again three questions. The interviewer stated, "I want to have a good discussion; if you are unable to give the correct answer, it's okay, but the correct answer will matter." The first question was similar to 'House Robber 3' on LeetCode, except it was on an n-ary tree. In the second question, I was given a binary tree and had to remove an edge such that the height difference between the resulting two trees was maximized. I had to return this difference of heights.

In round 3, I was asked a few questions about my life and journey, along with some design questions based on OOPS.
