In many online technical assessments, you’ll typically encounter two major segments. First, you’ll face coding challenges—often two problem-solving tasks that test your algorithmic thinking and familiarity with data structures. Then comes a workday simulation, where you respond to a series of emails as though you’re at work, tackling tasks, providing solutions, and prioritizing requests. This simulation checks your communication skills, time management, and teamwork approach by having you explain technical decisions, outline steps to resolve issues, and address multiple concurrent tasks—just like in a real-world environment.

Question 1
We’ve received multiple customer complaints about slow response times in the new feature we rolled out last week. Could you walk us through your approach for diagnosing performance bottlenecks in our service and propose how we could optimize it for faster throughput? Please include any metrics or tools you’d use, and provide an estimated timeline for resolution."
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.

Question 1
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.

Question 1
Questions were mainly hashmap, sliding window and interval related.
Interview by recuriter, Phone interview over Chime with one easy Leet code problem and 2 behavioral questions. Although the interviewer was very casual at the start of the conversation, it quickly changed into behavioral questions at the start.
