FPL Technologies interview questions

The interview process consisted of six to seven rounds in total: 1. Assignment – The process started with a take-home assignment/coding task designed to evaluate problem-solving ability, code quality, and understanding of core concepts. 2. Technical Round 1 – A hands-on technical discussion focused on data structures, algorithms, and practical coding skills. This included live problem-solving and whiteboard/collaborative coding exercises. 3. Technical Round 2 – A deeper technical evaluation that covered system design, architecture, scalability, and sometimes advanced coding challenges. 4. High-Level Design (HLD) – A round dedicated to high-level system design, where I was asked to architect solutions for real-world problems. The focus was on scalability, fault-tolerance, and trade-offs between different approaches. 5. Low-Level Design (LLD) – A detailed design round that went into class structures, database schema, APIs, and implementation details. This tested how well I can translate an HLD into an executable design. 6. VP of Engineering – A leadership and culture-fit round with the VP of Engineering. Questions were around ownership, past projects, leadership qualities, and alignment with company values. 7. CTO Round – The final round with the CTO, which was more about vision, alignment with company goals, and understanding how I could contribute at a strategic level.

Interviewer was really friendly, started by asking about me and my interests. Later on he moved to discussion on my CV, Grilled me on my CV, asked Backend SDE questions related to them, this went for majority of interview and then at end he asked a DSA question related to Dynamic Programming, Leetcode Medium.
