My interview at Amazon covered algorithm coding, design, and teamwork.

In the technical rounds, I solved common algorithm problems such as finding the longest substring without repeating characters, merging k sorted lists, and implementing an LRU cache, while explaining time and space complexity.

The design questions focused on using patterns like Factory, Singleton, and Observer, and building scalable systems such as a URL shortener or notification service.

In the behavioral round, I discussed how I handle team conflicts, take ownership, and deliver under pressure, showing how I align with Amazon’s leadership principles.

Algorithm & Coding:

"Find the longest substring without repeating characters."

"Merge k sorted linked lists."

"Implement an LRU cache."

"Given a binary tree, return its level order traversal."

"Find the kth largest element in a stream."

Design & System Thinking:

"Design a URL shortener like TinyURL."

"Design a scalable notification system that supports millions of users."

"How would you use design patterns like Singleton or Observer in a real project?"

"How do you ensure fault tolerance and scalability in a distributed system?"

Behavioral / Teamwork:

"Tell me about a time you disagreed with a teammate — how did you handle it?"

"Describe a time you took ownership of a problem beyond your scope."

"Give an example of when you delivered under tight deadlines."

"Tell me about a time you improved a process or system in your team."
