Flipkart SDE 3 | Bangalore | 6 YoE

I underwent a comprehensive interview process for the SDE 3 role at Flipkart in Bangalore. The first round was a 90-minute Machine Coding challenge where I had to design an in-memory message streaming service supporting multiple topics, producers, and consumers, ensuring order, thread safety, and real-time streaming.

Following this, Round 2 was a 30-minute Machine Coding Evaluation, where my solution from the previous round was thoroughly discussed, focusing on modularity, OOP principles, design patterns, and concurrency.

Round 3 was a 60-minute Problem Solving / Data Structures round. I was asked to solve two LeetCode problems: Course Schedule II and Design a Stack With Increment Operation.

The System Design round, lasting 90 minutes, required me to design a quick commerce system similar to Flipkart Minutes.

Finally, the HM Round was a 60-minute discussion where we delved into my past projects and my role in them, along with deep dives into system design topics like Caching, CDNs, and Networks. I was ultimately selected for the role.
