Entrevista
Timeline:
Online Assessment: January 2025
Loop Interviews: April 2025
Round 1 – Technical + Behavioral (SDE-2)
Duration: 1 hour
0.5 hr Behavioral: Focus on Amazon Leadership Principles. Asked about ownership, bias for action, and delivering results.
0.5 hr Technical: Unbounded Knapsack problem – minimize box combinations to reach a target.
-I explained the brute-force recursive approach, then optimized using top-down DP with memoization.
Follow-up: Asked to modify the solution for Bounded Knapsack (each box can be used only certain no of times).
Round 2 – Managerial Round
Duration: 1 hour
Experience: Disorganized and unclear.
-Interviewer was confused, used a personal laptop, and struggled with tech setup (mic/camera on/off).
-No question was shared via the code editor.
-Verbally described a vague Elevator System Design OOP problem and kept adding unrelated helper methods.
-Frequent interruptions, poor structure, and lack of clarity.
Feedback: Amazon should evaluate interviewers based on their ability to conduct structured, effective interviews—not solely on seniority.
Round 3 – Technical + Behavioral (SDE-2)
Duration: 1 hour
0.5 hr Behavioral:
Question 1: Delivered a critical project under a tight deadline. Asked to elaborate on trade-offs and sacrifices made.
Question 2: Made a long-term decision sacrificing short-term gain. Asked to explain the rationale and business impact.
0.5 hr Technical:
Simulated Unix find command functionality.
1: Search and return all files over a certain size ( 5MB) in a directory tree.
2: Search and return all .xml files in a directory.
-Implemented recursive DFS traversal with filtering logic.

Pergunta 1
Technical rounds were structured and focused with clear problem statements. However, the managerial round was disorganized and poorly executed—Amazon should ensure senior-level interviewers are prepared and not improvising mid-interview.
Interviewed for silicon team. Have only been asked about the domain specific knowledge in 1st round and system design in 2nd round and C coding in 3rd round.
The interviews were 50 mins each.
The phone screen went longer than expected, focusing heavily on implementation details. The interviewer really grilled me on my approach to a Least Recently Used (LRU) cache, asking how I'd combine a hashmap with a doubly linked list. I felt well-prepared since I had gone through system design examples on PracHub, which made me comfortable discussing eviction policies. The later rounds included more technical questions and behavioral interviews, but in the end, I received an offer, though I ultimately decided to decline. Overall, I’d say the process was average, with solid questions.

Design and implement a Least Recently Used (LRU) cache supporting get(key) and put(key, value) in O(1) average time. Walk through combining a hashmap with a doubly linked list, eviction policy when capacity is exceeded, and how you'd extend it to handle thread-safe concurrent access.
Recruiter reaches out after applying through Amazon careers, no referral. Had an initial OA, then after a month had four rounds in two days - three coding one system design. Each round had 30 min behavioral and 30 min coding.

Questions were mainly hashmap, sliding window and interval related.
