Interview Process at Amazon:
I received a call from HR informing me about the interview process. The complete process consisted of the following rounds:
Online Test (Round 1):
This was the initial screening round.
It included 2 DSA coding questions:
One was based on Dynamic Programming (DP)
The other was based on Graphs
Technical Interviews (Rounds 2 & 3):
Two rounds focused on core data structures, algorithms, and problem-solving skills
Questions covered optimal approaches and real-time debugging
Perguntas de entrevista [1]
Pergunta 1
They asked me two DSA questions during the interview:
LeetCode 767 – Reorganize String:
I started by explaining the brute-force approach to the problem. After that, they asked me to come up with an optimal solution. I was able to derive the correct optimal approach during the discussion, but I couldn’t implement the most efficient version within the interview timeframe. At first, the problem seemed difficult under pressure, but in hindsight, it turned out to be quite manageable.
LeetCode 22: Generate Parentheses
I understood the problem well and was able to explain the optimized backtracking solution. However, due to time constraints, they didn’t ask me to write the code.
Loop — 4 rounds, all on the same day
Round 1 — Coding (DSA)
Interviewer was a senior SDE, very friendly.
Warm-up + behavioral: "Tell me about a time you took ownership of something outside your responsibilities."
Main question: Given a list of meeting intervals, find the minimum number of conference rooms required. I used a heap. He then asked a follow-up: what if meetings could be reassigned to minimize total idle time? We discussed approaches but didn't fully code it.
He cared a lot about how I talked through edge cases out loud.
Round 2 — Coding + Problem Solving
LP question: "Describe a situation where you disagreed with a teammate."
Coding: LRU Cache implementation from scratch. I used a hashmap + doubly linked list. He pushed on thread-safety and what happens at capacity 0.
Round 3 — Behavioral (Bar Raiser)
This was the toughest round — no coding, all Leadership Principles, very deep STAR-format probing.
Questions I got:
"Tell me about a time you failed and what you learned."
"A time you had to deliver something with a tight deadline and limited information."
The bar raiser kept drilling: "What was your specific contribution?" "What would you do differently?" "What data did you use?" Have 6–8 strong stories ready with metrics.
Round 4 — Low-Level Design
Design: Design a parking lot system (classes, vehicle types, spot allocation, pricing). Then he asked me to code the findSpot() and releaseSpot() methods.

Most coding questions were LeetCode Medium. Common themes: graphs, heaps, sliding window, hashmaps, and LRU/design., system design,
Great interview process with three rounds, including a technical assessment and a technical interview. The interviewers were professional and supportive throughout the process. The questions mainly focused on DSA, problem-solving, and core technical concepts. The discussions were engaging and provided a good opportunity to demonstrate technical skills. Overall, the process was well-structured, smooth, transparent, and a very positive experience.
Candidatei-me por meio de uma faculdade ou universidade. Fiz uma entrevista na empresa Amazon (Dublin, Dublin).
Entrevista
Online techincal assessment. Had to screen share and complete basic coding tasks similar to Leet Code. Could choose a language of your choice. Overall a very fair system and judged based on merit.

Pergunta 1
Technical assessment so a basic leet code style question about reversing the orders of long numerical strings.
