Coding Technical
Had a good experience, the interviewers were super friendly. They asked me the exact questions I wanted to be asked. I requested Two Sum and they gave it to me. I asked for Burst Balloons and they did too. I even ended up teaching the interviewer about segment trees and Fenwick trees, and when to use each one.
Confirmed questions1 question
- For a given situation, which is more appropriate: prefix sum or segment tree.

Technical Coding System Design Behavioral
It started with a quick 30 min recruiter chat to go over my background and see if I was a good fit. Then, I had two technical phone interviews back to back. The first was a live coding session focusing on data structures, and the second was about system design. To wrap things up, I had a virtual chat with the CTO for a behavioral and culture-fit discussion. After that, they extended an offer.
Confirmed questions2 questions
- Describe the design for a globally distributed, strongly consistent key–value store capable of low-latency reads and writes across different regions.
- Explain your approach to data partitioning, replication, consensus protocol, and failure recovery for such a system, and how you would manage the trade-offs between consistency, availability, and performance during network partitions.

Coding
It was a 3-round process. All 3 rounds were technical, focusing solely on Data Structures and Algorithms (DSA). The first round involved a dynamic programming (DP) question, specifically a 'take, not take' type, for which I provided a satisfactory solution. The second round was about a Binary Tree (BT) problem. I initially found it challenging, but the interviewer was very helpful and guided me through the coding part.
Confirmed questions2 questions
- A dynamic programming question involving a take/not take scenario.
- A question related to Binary Trees.
