Round 1 - The interviewer started with a small introduction of both of us. He asked about OOPs concepts and my current project. Then he directly goes to the coding question, he asked me 2 coding questions. one is based on a tree and the other is based on a graph. After that, he asked me same questions but to solve this with another approach and optimize more this solution. Then he asked me one question on Amazon Leadership Principle. This round goes for 65 mins. Round 2 - The interviewer started with a small introduction of him and then directly started with coding questions. In this round he asked me 4 questions. 2 are based on a tree and 2 are based on graphs. Before starting the coding at every question they ask for an approach for this problem. This round goes for 70 mins. Round 3 - It is the Managerial round. He asked me questions related to My Project, Operating System, DBMS, SQL queries, one coding question, one Amazon Leadership Principle question, and one behavioral question. He asked me in-depth questions about my project. This round goes for 80 mins. In every round, they check your problem-solving skills, your approach from worst to the best solution, and your thought process. Also, after each question, the complexity of the algorithm was asked. It's good to ask questions to get more clarification about the question. They are very friendly while taking the interview.
DSA questions based on binary trees and dynamic programming
I should not reveal the particular questions but they ask normal DS Also questions every companies ask. Topics could be DP, Trees, Graphs, etc. Nothing fancy though that u wouldn't have seen before. First 2 round had 2 questions each. And it can go on for an hour at most. Third round was with the Manager. I was asked detailed conceptual questions around Multithreading, Inheritance, Memory management etc. He seemed to be very smart as he was going into depth of each question. In all three rounds, i was also asked couple of LP questions like Tell me about something u innovated Tell me about something u recently debugged Tell me about the issue that u fixed on production Remember not to lie in LP questions, because they can verify things on internet and counter question you. It happened in my case, not that i lied but he wanted to verify whatever i was saying.
