I had an online interview on September 13, 2024. The interview process involved solving two questions within 90 minutes. After that, I had two more segments where I had to make workday-related decisions. For example, I was asked to determine which databases I would use to build a voting system with product requirements for a 5-minute duration and display live voting counts.
Interview questions [2]
Question 1
Create a function that takes a slice of 32-bit integers and a number of channels, k, as input. The goal of this function is to split all the integers from the array between the channels (arrays) in such a way that it maximizes the sum of the medians of all the channels. It's important to note that each channel must hold at least one integer.
You are given a string `s` of length `n`. Your task is to return the next nice string based on lexicographic order of len n. A nice string is defined as a string in which no two adjacent characters are the same. For example, "abb" is not a nice string because "bb" are duplicate adjacent characters.
Please note that if the string contains "zz", it cannot be transformed into a nice string, and in such cases, you should return "-1". Additionally, the character 'z' cannot be increased as it is the last character and cannot be transformed into 'a'.
Tough interview.
The Process: Automated Online Assessment (OA) with 2 coding questions and a system simulation, followed by a 4-round virtual Loop. Every single round started with 20 minutes of intense, behavioral behavioral questions diving into Amazon's Leadership Principles, followed by 25 minutes of technical coding or system design.
Amazon interviews are a test of mental endurance because you have to switch from deep behavioral storytelling straight into complex coding which can be so difficult. I used Apex Interviewer to practice the cognitive context switch. Running through their live-coding workspace helped me ensure my technical communication and architectural structures remained sharp and automatic, even after spending the first half of the interview defending my past project metrics. I fed the practice AI questions I extracted from glassdoor and gothamloop.
In the end, the offer was way lower than I hoped.

Design the backend inventory tracking and placement service for a global fulfillment network, ensuring strict transactional consistency across multiple regional warehouses during peak shopping events.
Initial screening call with recruiter followed by a 1 hr hacker rank question on DSA. The final round was a panel consisting of 4 interviews ranging from technical design, more DSA and behaviour questions.

Question 1
Describe a time when you disagreed with your team and how you resolved it
Online Application & Assessment: Candidates apply via amazon.jobs and may be asked to complete online assessments (work simulations or technical tests).
Recruiter Phone Screen: A 30-60 minute interview to discuss your background, interest in the role, and initial behavioral questions.
Technical Phone Screen (For Tech Roles): A 60-minute interview focused on data structures, algorithms, and coding in a shared editor.
Interview Loop (Virtual/Onsite): The final stage, usually 3-5, 45-60 minute interviews held on the same day or over a few days.
Behavioral Questions: These focus on past behavior (STAR method: Situation, Task, Action, Result) mapped to Leadership Principles.
Technical/Functional Questions: Problem-solving, system design, or domain-specific questions.
Bar Raiser Interview: One interviewer is a "Bar Raiser," a neutral employee from another team tasked with ensuring hiring standards remain high.
Hiring Committee/Debrief: Interviewers meet to discuss candidate feedback and make a hiring decision.
