There were 3 rounds of interview. In first round, there were 2 questions and i had to explain and code both. First question was based on merging intervals and in other question a binary tree was given and I had to find the size of a subtree in which all the nodes have value 0. in round 2, again there were three questions and the interviewer said "I want to have a good discussion, if your are unable to give correct answer its okay, but correct answer will matter." first question was same as "house robber 3" on leetcode, except it was n-ary tree. In second question, I was given a binary tree and i had to remove and edge from the tree such that resulting two tree's heights difference is maximum. I had to return the difference of heights. In round 3 i was asked a few questions about my life and journey along with some designing questions based on OOPS
