The BEL interview was conducted by a professional panel of four members who began the session with a standard introduction and several general background questions. The discussion quickly transitioned into a rigorous, deep-dive examination of my resume, where the panelists scrutinized every project in detail, questioning the technical choices and implementation strategies I employed. Following this, they focused on my internship at TATA Electronics, asking specific questions about my responsibilities and the industry-level exposure I gained during my tenure. The interview then shifted toward the communication domain, with a series of technical questions centered on core engineering principles and signal theory. To conclude, the panel asked standard HR and behavioral questions to assess my cultural fit for the organization before bringing the session to a close.

## 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.
