## 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.

## Interview Overview I attended the interview for the AI Internship Programme at the City Union Bank Centre of Excellence, SASTRA University. The interview was around 15 minutes long and focused mainly on my technical background, machine learning project, SQL knowledge, and basic banking concepts. The interview was conversational and the interviewer asked questions based on the skills and projects mentioned in my profile. This made it important to understand my projects properly rather than simply memorizing theoretical answers. ## My Project Discussion A major part of the interview was based on my Telecom Customer Churn Prediction project. I was asked to explain the project, the problem I was trying to solve, the dataset, preprocessing steps, and the machine learning models I used. I explained how I performed exploratory data analysis, identified missing values, handled categorical variables through encoding, prepared the data for modelling, and divided it into training and testing datasets. I had experimented with multiple machine learning algorithms, including: - Logistic Regression - Decision Tree - Random Forest I also discussed the evaluation metrics used to compare the models, including accuracy, precision, recall, and F1-score. One important takeaway from the project discussion was that you should be able to explain not only what model you used, but also WHY you used it and how you decided which model performed better. ## SQL and Technical Questions The interview also covered SQL and basic technical concepts. Revising SQL before the interview was useful, especially concepts such as filtering data, aggregation, grouping, joins, and writing queries to retrieve meaningful information from tables. The interview also tested my understanding of basic machine learning concepts rather than only asking me to write code. For students preparing for similar interviews, I would recommend being comfortable with: - Python fundamentals - Pandas and NumPy - SQL queries - Machine learning fundamentals - Data preprocessing - Classification algorithms - Model evaluation metrics - Basic statistics - Exploratory Data Analysis ## Banking Concepts Since the internship was related to banking and customer analytics, I was also expected to have an understanding of basic banking concepts. The preparation included concepts related to customer analysis, banking products, transactions, and how data analytics can be used to understand customer behaviour. Having a basic understanding of banking terminology is useful when applying for AI or Data Science roles in the BFSI domain. Technical knowledge alone may not be enough when the internship involves solving business problems using financial or customer data. ## What I Learned One of the biggest lessons from the interview was the importance of understanding your own resume. If you mention a machine learning project, be prepared to explain the complete workflow: 1. What problem are you solving? 2. What dataset did you use? 3. What preprocessing did you perform? 4. How did you handle missing values? 5. How did you encode categorical variables? 6. Which models did you try? 7. Why did you choose those models? 8. Which evaluation metrics did you use? 9. Which model performed best and why? 10. What could you improve in the future? The same applies to programming languages and tools mentioned in your resume. Interviewers can ask questions from any skill you list. ## Preparation Tips For students preparing for AI/ML internships, I would recommend focusing on fundamentals instead of trying to learn too many advanced topics at the last minute. Revise Python, SQL, machine learning algorithms, EDA, preprocessing, and evaluation metrics. At the same time, understand your projects deeply and practice explaining them in simple language. For banking-related AI roles, spend some time learning basic banking concepts and customer analytics terminology as well. Most importantly, don't just memorize definitions. Try to understand how a concept would actually be used to solve a real-world problem. ## Final Takeaway The interview was a good opportunity to connect my academic knowledge and machine learning project experience with a real-world banking use case. It also showed me that for internship interviews, strong fundamentals and the ability to clearly explain your own work are extremely important. If you are preparing for a similar AI/Data Science internship, focus on your projects, Python, SQL, ML fundamentals, and domain-specific concepts. Be honest about what you know, and make sure you can confidently explain everything mentioned on your resume.
