CHUBB Interview Experience

Recently, I had the opportunity to interview with CHUBB, a world leader in insurance with operations in more than 56 countries. The interview process consisted of two rounds: L1 (Technical Interview) (40 min )and L2 (Technical + Managerial Interview) (20 min). Here’s how my experience went:

L1 — Technical Interview: The first round was purely technical and focused on my projects, core concepts, and problem-solving skills. The flow of questions was: -Self-Introduction -Detailed discussion on my projects (including the complete tech stack, architecture, and real-world application). -Why did I choose React over Angular? -Explain OOPs concepts with real-world examples. -What is Polymorphism? -JWT and Middleware — what they are and their use cases. -Difference between Abstract class and Interface. -Different Access Modifiers. -What is the Virtual DOM? -What is Machine Learning (ML)? -Types of ML. -What is a Confusion Matrix? -What is an API and why do we use it? -Use of the base keyword in C++. -What is an MCP Server? -DSA Question → Valid Sudoku (shared a LeetCode link). -Difference between Delete, Drop, and Truncate in SQL. -Difference between WHERE and HAVING. -SQL query to find the second highest rating. -Logical questions on SQL manipulations. -What is Context Switching in operating systems? -Why OOPs is important? -What is Normalization in databases and why it is used? This round was a deep mix of coding, CS fundamentals, and project-based discussions.

L2 — Technical + Managerial Interview: The second round focused on both technical and personality aspects. -Self-Introduction -Detailed discussion on my projects again (this time more focused on problem-solving and scalability). -My extra-curriculars and club activities — leadership and management roles I undertook. -Discussion on Agentic AI and RAG (Retrieval Augmented Generation). -Java Backend concepts and related questions. -A couple of HR-style questions to test cultural fit and motivation.

Final Verdict : SELECTED I’m glad to share that I was selected! 🎉 The interview process was thorough, covering everything from DSA, SQL, and OOPs to ML, system concepts, and my personal interests. What I really liked was how the panel not only tested technical knowledge but also assessed project depth, communication skills, and problem-solving approach.

Key Takeaways : -Be thorough with your projects — know every detail of your implementation and tech stack. -Revise core CS fundamentals — OOPs, DBMS, SQL, OS, and DSA. -Keep up with trending concepts like AI, RAG, and backend systems. -Confidence and clarity in communication make a big difference.
