Envié una solicitud electrónica. El proceso duró 3 días. Acudí a una entrevista en Amazon (Seattle, WA) en mar 2021
Entrevista
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

Pregunta 1
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.”
Interview involved one screening OA and one final day, 3 back to back interviews, one technical, one behavioral and one mix. Focused on leader ship principles and DSA and algo
Good and better interview so far its worth giving a try rather than not. Good interviewer pleasant speaking and comfortable so far its worth giving a try rather than not good interviewer pleasant speaking and good
The process began with an Online Assessment (OA) featuring two coding challenges and a work style simulation. This was followed by a technical phone screen. The final round consisted of 4–5 virtual onsite interviews covering Data Structures & Algorithms, System Design, and a heavy emphasis on Amazon's Leadership Principles.
