J'ai postulé via un recruteur. Le processus a pris 1 jour. J'ai passé un entretien chez Amazon en avr. 2010
Entretien
Got a call from company's recruiter and have a phone interview. The recruiter is very proactive since I originally only get an email and I did not respond to it. Then a week or two later the recruiter called me.
The phone interview is long (around 1hr 15min) The interviewer did not ask many questions on my job but instead ask me several technical questions.
The interviewer is fair but he did not volunteer any hints.
Questions d'entretien [1]
Question 1
Given a binary tree, how do you create a function that can swap the binary tree? (i.e. the left child becomes the right child and vice versa)
From this function you just created, can you create another function that will swap the tree in Alternate level? (i.e. swap 1 level and then the next level does not swap)
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.
Questions d'entretien [1]
Question 1
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.
J'ai postulé via un établissement d'enseignement supérieur ou universitaire. J'ai passé un entretien chez Amazon (Dublin, Dublin)
Entretien
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.
Questions d'entretien [1]
Question 1
Technical assessment so a basic leet code style question about reversing the orders of long numerical strings.
