How to prepare
- Even if the interviewer doesn’t ask for an optimized solution, always strive for the optimal one. It shows maturity in your problem-solving approach.
- For System Design, don’t overcomplicate. Clarify assumptions, think out loud, and show curiosity.
- Focus on DSA patterns like sliding window, heaps, and string manipulation not just solving, but writing clean and correct code under pressure.
Round by round

DSA Round 190 min
The round started with a short introduction. The interviewer was polite and asked a few basic questions about the tech stack I’ve worked with earlier, just to understand my background. Soon after, we moved to coding questions. It was a sliding window question. I had solved it before, so I felt confident and completed it smoothly. After the round, I felt quite positive and thought I had done well. But when the feedback came, I saw that only one of my solutions had passed completely. The second one got only partial marks.

High-Level Design Round90 min
This round was taken by SDE-3,and it was clear right from the start that he was very technically strong. We began with a deep dive into my past projects. The conversation got interesting when he asked why I picked certain technologies like MySQL instead of MongoDB, or Kafka over RabbitMQ. I also explained how I used Kafka Streams with binlogs instead of batch processing, and why that choice made sense in my use case.

Low-Level Design Round60 min
I was asked to design a Hotel Management System that could handle multiple hotels, different room types, and manage concurrent room bookings. I began by explaining the overall structure using clear class diagrams, covering key components like Hotel, Room, Customer, and Booking. I made sure the design was modular and easy to scale if more hotels or room types were added later. To handle concurrent bookings, I walked through how the booking service would work and the kind of locking strategies.

Team Fit Round45 min
This round was more of a conversation-style discussion than a technical deep-dive. It started with me sharing some of the technical challenges I’ve faced in my previous roles and how I handled them. We also talked about the scale I’ve worked on and the engineering practices I follow in day-to-day work including how I approach problem-solving.

Functional Fit + Values Round30 min
This round focused on both technical mindset and business understanding. It started with a discussion around my past career decisions and then moved into the most business-impacting projects I’ve worked on so far. The interviewer asked me to share some problems I observed in my previous company and what I would do to fix or improve them. The overall aim was to understand how I think about product, business, and tech together, and how I approach building solutions that drive value.
