I applied online. The process took 2 weeks. I interviewed at Amazon in Dec 2021
Interview
I applied for the SDE-1 Role from the amazon career page. After applying I received mail to of coding round. The coding round was 105 min. There was 4 question, 2 were coding questions and 2 are a description of this code. The expectation from the coding round is optimized coded solution, time, and space complexity.
After successful completion of the coding round, there were 3 rounds of interview. 2 rounds are Technical rounds and 1 is Managerial rounds. All three interviews will be done in one day.
Interview questions [1]
Question 1
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.
Interview includes 2 coding rounds, 1 system design round, and STAR-based behavioral questions. Focus on DSA, especially graphs and trees. Also prepare Gmail filtering, timestamp-based filtering, and related implementation concepts.

I attended an SDE 1 interview at Amazon. The interviewer focused on data structures, algorithms, and problem-solving. I explained my approach clearly, optimized my solution, answered behavioral questions, and gained valuable interview experience.
Asked for intro, then 2 dsa question and 1 question on lp. Explain your thought process and start with brute force dry run it explain its tc and sc and theb jump on to optimised solution
