Tata Consultancy Services Software Development Engineer SDE interview questions

it was a multi-round process. It started with an online coding assessment—two algorithmic problems focused on arrays and graphs. I solved both within time, optimizing for space and time complexity. Next came the technical interview. The interviewer asked me to implement a trie data structure and discuss its use cases. We then dove into system design—I was asked to design a URL shortening service. I explained the architecture, database schema, hashing techniques, and scalability considerations. The third round was behavioral. I was asked about a time I faced a technical challenge and how I resolved it. I shared my experience debugging a deployment issue in Visual Studio Code, emphasizing my problem-solving approach and teamwork. Finally, the hiring manager discussed the team’s goals and asked how I stay updated with emerging technologies. Overall, it was a rigorous but rewarding experience that tested both my coding skills and my ability to think holistically about software systems.

Technical Round followed by HR round. Technical Round went on for 30 mins with all questions related to my projects. last few mins few MR questions were asked pretty basic on how i would manage so and so situation.
