Nykaa SDE Interview Experience

I recently interviewed for an SDE role at Nykaa and got selected. Sharing my interview experience for anyone preparing for the process.

Round 1 — DSA

Two questions were asked:

1. Course Schedule
2. Max Consecutive Ones III

Both were based on standard DSA concepts. The round mainly focused on problem-solving approach and complexity.

Round 2 — LLD

The question was:

Design Splitwise

The discussion covered the overall object-oriented design and how the different components would interact.

Round 3 — System Design [The third round was listed as a Leadership round, but the questions focused on High-Level Design (HLD), problem-solving, and handling concurrency in an e-commerce system.]

Two main questions were asked:

1. Design the complete order flow, starting from the cart and covering the different stages of an order.
2. Inventory concurrency: How would you handle a scenario where N users try to purchase the same item at the same time?

The second question focused on handling concurrent inventory updates and avoiding overselling.

Overall

The interview process had a good mix of DSA, LLD, system design, and concurrency.

Overall, it was a great experience, and I'm happy to share that I got selected at Nykaa! 🚀
