Sliding WindowI recently had the opportunity to participate in the Infosys on-campus recruitment drive at IIT Dharwad. I’m happy to share that the process concluded with an offer for the Specialist Programmer (SP) L2 role. Here is a detailed breakdown of my experience: Round 1: Online Assessment (OA) The assessment consisted of 4 coding problems categorized by difficulty: Easy, Medium, Hard, and Complex. Performance in this round determines which role you are mapped to (DSE, SP-L1, SP-L2, or SP-L3). My Performance: I have solved 2.3 question out of 4 ( easy full , medium partial and for hard 11/12). Difficulty Level: The "Easy" and "Medium" questions were comparable to LeetCode Medium. The "Hard" question was LeetCode Hard, and the "Complex" one felt like a high-rated Codeforces problem. Key Takeaway: The entire set was heavy on Dynamic Programming. Solving the "Hard" problem is mandatory to be shortlisted for the SP-L2 and SP-L3 roles. Round 2: Technical Interview (at Infosys Hubli Campus) I was shortlisted for the SP-L3 interview process based on my OA score. The interview took place in person at the Infosys Hubli campus. Atmosphere: The interviewer was very friendly. He skipped the standard "introduction" formalities and jumped straight into a technical discussion. Code Discussion: He reviewed my OA submission extensively. I was asked to explain my approach and logic for every problem I attempted during the assessment. System Design: We spent about 40 minutes discussing a System Design problem: "Design a URL Shortener (like TinyURL)." This was an in-depth discussion covering database choices, scaling, and hashing logic. Verdict: Selected for the Specialist Programmer L2 role. Grateful for the opportunity and looking forward to the journey ahead!

## I was not selected for Bharat Electronics Limited (BEL). One of the main reasons could be that during the discussion I clearly mentioned that I am more interested in the startup and business ecosystem rather than a traditional long-term corporate job. Below is a detailed breakdown of how BEL conducted the recruitment process in our college. # Techncial Test BEL conducted an OMR-based written test consisting of 85 questions with a 2-hour time limit. Question Distribution - Most questions were from core electrical engineering subjects, including: Electromagnetism Electrical Machines Control Systems Analog Electronics Digital Electronics Out of the 85 questions, around 15 questions were general aptitude. These aptitude questions were relatively straightforward and could easily be solved by a student of around 8th–9th standard level. ## Nature of Questions Most technical questions were memory-based rather than complex problem-solving. Many required recalling formulas or theoretical concepts rather than performing long calculations. Some numerical questions were present, but they were direct and not very time-consuming. After the written test, around 10 students were shortlisted for the interview round. #Important Note Before the written test, there was a strict document verification process. Special attention was given to caste certificates, which needed to be issued by the Central Government format, not only by a state authority. Other required documents included: 10th marksheet 12th marksheet College marksheets Aadhaar card Other supporting documents # Interview Round The interview overall went well. Most of the questions were based on my resume and projects. Questions Asked The interview panel asked: Details about the projects mentioned in my resume Technical questions related to electrical engineering fundamentals Questions about my interest in startups Since I mentioned that I am actively working on a startup idea, they asked: If you are already interested in building a startup, why do you want to join BEL? They also asked a personal question related to my background: Since you are from North India, why are you not preparing for IAS instead of pursuing an electrical engineering job? ## Overall Interview Focus The discussion mainly focused on: My technical projects Basic electrical engineering concepts My career interests and long-term plans Overall, the interview was positive and interactive. # Questions Asked in the Interview The specific technical questions asked during my interview are listed in the question section below.

## 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.

Verified PrepLinc profile for sharing official interview guides, company insights, and structured preparation material.
Infosys is coming to campus! This guide, compiled by the PrepLinc team with insights from students at IIT Palakkad, covers everything you need to know about the Online Test for the role like Specialist Programmer (SP) and Digital Specialist Engineer (DSE).
The test is typically conducted on the Infosys assessment platform and consists of three sections. The total duration is approximately 100 minutes.
Section 1: Mathematical Ability & Reasoning (25 mins): This section tests your logical and quantitative skills. Expect questions on puzzles, data interpretation, and pattern recognition. Time management is key here.
Section 2: Technical Ability (35 mins): A multiple-choice section covering core CS fundamentals. Key topics include Data Structures, Algorithms (especially complexity analysis), OOPs concepts, DBMS, and basic Operating Systems knowledge.
Section 3: Coding (40 mins): This is the most crucial section, containing two coding problems. Typically, one is of easy-medium difficulty (often array or string-based) and the second is a medium-hard problem (often involving Dynamic Programming, Graphs, or complex data structures like Heaps).
Based on recent experiences, a strong performance in the coding section is vital. Aim to solve at least one question completely and make significant progress on the second. Don't neglect the technical MCQ section, as it often acts as a tie-breaker.
