Amazon interview experience | Set 398 (On-Campus)
The online round was hosted in HackerEarth platform. It had 20 MCQ’s of 1 mark each and 0.25 negative mark and 2 coding questions of 10 marks each. The MCQ’s was mostly from Data Structures and Operating Systems, and few questions from networking, DBMS and 1 Java question.Â
After clearing online round there were 3 technical round and 1 bar raiser round.Â
Resume was taken before interviews.Â
In this round, the interviewer asked about my coding and scholastic achievement.Â
1. Favorite subject and questions on that topics. Â
2. Basic question on space and time complexityÂ
4. Write a program to find number of shapes in Boolean matrix. https://www.geeksforgeeks.org/find-number-of-islands/. He asked me about time complexity and space complexity. At the beginning space complexity of my solution was O(mn). I presented 4 methods and reduced its complexity to O(1). I solved it by both dfs and bfs.Â
In this round, the interviewer asked me to introduce myself and short discussion on my resume projectÂ
In this round, the interviewer asked me about my resume project and deep discussion on my projects.Â
2. Question on computer science fundamentals. Detailed explanation of virtual memory, paging page faults etc.Â
This round was based on designing problems. Â
In each round interviewers were giving test cases to run on the programs and expecting very neat and clean code.Â
So I would recommend to have experience of competitive coding for depth knowledge of code and then follow geeksforgeeks. It has all the problems.Â
Before 2-3 of campus recruitment I would recommend to solve all problems of interviewbit with the help of geeksforgeeks.Â
