Okay, here's my interview experience with Amazon for an internship position. Unfortunately, I was rejected after the technical round, which I found to be of medium difficulty. Let me walk you through it. # The Process The interview was technical and started with brief introductions. We then jumped straight into two Data Structures and Algorithms (DSA) questions. The first was based on binary search, specifically searching on answers. I managed to solve it partially but struggled with the edge cases. The second question was about finding the Lowest Common Ancestor (LCA) in a binary tree. I solved it, but my solution was a bit complex. # Topics Covered & Difficulty The interview focused on Data Structures and Algorithms. One question involved a medium-difficulty binary search problem where I had to efficiently search for an optimal solution within a range, but I struggled with some edge cases. The second question was a standard tree problem, specifically finding the Lowest Common Ancestor in a Binary Tree. While I solved it, I made it a bit more complex than necessary. You can find the exact wording of the questions I was asked in the dedicated section below. # My Thoughts on the Culture Amazon is one of the best companies in the world, and it definitely has a great company culture. The environment seemed very focused and driven, with a strong emphasis on problem-solving and innovation. # Advice for Others My main advice would be to write clean, well-documented code and explain your thought process clearly. The interviewer specifically told me to improve my code writing and explanation skills. Even if you solve the problem, poor code quality or a lack of clear communication can be a reason for rejection. Focus on making your code easy to understand and articulate your reasoning behind each step. Good luck!

## I am sharing my interview experience with ICICI from last year -2025. I applied it through my campus placement drive as a fresher. ### ICICI came to IIT Delhi's placement season 2024–2025. It was listed as an ICICI Manager I. Manager I is a grade. It was open for all departments with no minimum CGPA criteria. # My profile at that time: I had an intern at a startup where I had built a recommendation model. I had been grinding LeetCode and Codeforces along with machine learning. I had successfully completed Andrew Ng's specialization course on ML and deep learning and practiced on Kaggle. # Online Assessment — 60 minutes At first we have CV shortlisting, where I got shortlisted. After that, I have to give an online assessment that contains only MCQ questions related to OOPs, DSA, Cpp, Java, and Python, which I successfully cleared. After that, I got a call from the placement cell that I have to give a personality test called personality profiler, where they asked me about how I will behave or react under some given conditions. Update 1—The interview shortlist comes on 30th November around 5 pm. Update 2—The interview was scheduled on the morning of 3rd December # Interview: It was 9 in the morning; the atmosphere was quite foggy and cold, and I was quite nervous. The interview is going to be the only one round with both technical and HR at the same time. ## They called me for Interview First question: “Tell about yourself.” I had prepared for this question and told about my name, my hometown, and my specializations along with my hobbies. Second question: “Explain any one of your projects.” I know this question will pop up, and I had prepared for this question by preparing my best project in depth. But as ICICI is a bank, I thought I should explain my project, which is relevant to the bank in any way. So instead of explaining about the project ‘AI Interviewer,’ I choose stock analysis by AI agent. I had been asked some cross questions regarding my project, which I answered successfully. Third Question: “Can you optimize the time taken to train ANN?” As there are many ways to optimize artificial neural networks. It starts with the hardware side, like using more powerful GPUs. Then I explained we can drop neurons in order to train the model faster. Then he asked me about some mathematical approaches, so I recalled Adam optimization, and I explained it in detail by drawing some formulas and images. Fourth question: “Forward and Back Propagation.” I started with forward propagation by considering a 2-layer neural network and similarly derived back propagation from it, which he seems satisfied with. ## Update 3 — Now my technical round is over and its for HR round 5. She asked me about why ICICI, my background, my future goals, and general HR questions, which I prepared before the interview and answered optimally, at least according to me. Update 4: I got a call from POC that they were willing to offer me, which I gladly accepted. I felt a surge of excitement and joy. Update 5: HR called me and congratulated me, after which we had a professional handshake and goodbye. 3rd December 2024 will be a special day for me as I get my first job. It was my first and last interview at IIT Delhi. Thanks for reading.

There is a techinical round and interview round happend in the same day(offline mode) where we were given an hour or so to write the test of MCQs which were mostly theoretical and some aptitudes. The level of the paper is moderate where the domains of questions were analog, communication, transmition lines, antennas and Signal processing. The imediately corrected the paper and given us the result for next round after half an hour. The interview rounds were friendly some comm. question like amplitude and frequency modulations, project explaination, Which modulation is less noisy all stuff. Then question of hobbies and general questions were followed.
