Amazon·Software Engineer·Onsite - Multi Round

Pending

Sep 2026

Two-round SDE intern loop at Amazon. Round 1 was rough on the DSA side (needed a hint, ran out of time), but the behavioral and project stuff went fine. Round 2 felt much better across the board. Now stuck waiting and second-guessing whether that one bad coding performance is a dealbreaker.

Walk me through a project you've worked on in depth.Tell me about a time you demonstrated strong customer focus. Give a specific example.Describe a conflict you had with a teammate or colleague and how you resolved it.+2 more

“This part went fine, maybe the best part of round 1 for me.”

Amazon·Software Engineer·Onsite - Multi Round

Rejected

Aug 2026

Went through the full Amazon SDE-1 loop in Berlin for the recent grad program and got rejected. Four interview rounds plus an online assessment, covering system design, algorithms, a GenAI-flavored coding problem, and behavioral questions. Sharing this in case it helps someone else prep better than I did.

You have a warehouse selling items to customers who submit bids. Each customer has an ID, a bid amount, and a desired item count. Highest bidders get served first; ties are broken by round-robin. Return the IDs of customers who received nothing.Design a shopping cart price calculator API: given a list of product IDs, return the total price. Plan for future discount logic and assume this runs at large scale.A rule is an ordered list of match keys like country, brand, and customer tier. Given a table of concrete values with a DEFAULT wildcard, and a query like (DE, acme, silver), return the matching result.+4 more

Aug 2026

Amazon SWE interview with a tricky array/binary string optimization problem. The question stumped even the LLMs apparently, which was a weird comfort.

Given an integer array called population and a binary string called unit, both of size n, where unit[i] = 1 means population[i] is protected: each 1 in the binary string can shift left at most once (from index i to i-1). Find the maximum total protected population after optimally repositioning the 1s.

“My approach was to find contiguous clumps of 1s and figure out whether the leftmost 1 in a clump should swap with the 0 to its left.”

Aug 2026

Went through a four-round Amazon SDE1 onsite loop over two days, all remote via Zoom with a live shared editor. Every round had both a coding problem and behavioral questions, which I wasn't fully prepared for. The technical depth varied a lot but one round felt like a real engineering conversation rather than an interview, which was a nice surprise.

Given a set of numbers and a target value, find a specific combination of elements that sums to the target (not just whether one exists).Walk me through a project you built yourself. What design decisions did you make, what are its limitations, and what trade-offs did you accept?How do you use AI tools in your day-to-day development work?+5 more

“The problem statement was deliberately vague and I had to ask a bunch of clarifying questions before I even understood what was being asked.”

Amazon·Software Engineer·Online Assessment (OA)

Prefer not to say

Aug 2026

Took an Amazon OA and the whole thing started on a rough note with the webcam showing a black screen and a 'no face detected' error even though my camera was working fine before and after. First coding problem was easy, aced it. Second one wrecked me.

Solve the first coding problem presented in the online assessment.Solve the second coding problem presented in the online assessment.

“Straightforward problem, passed all 15 test cases without much trouble.”

Someone prepping for the loop round at Amazon for an Associate Delivery Consultant AI/ML role, sharing what came up in their phone screen and asking what to expect next. The phone screen already hit low level design, AI/ML background, and a surprising amount of AWS-specific stuff.

Walk me through a low level design problem relevant to the role.Describe your experience working with AI and ML technologies.What is your hands-on experience with AWS services?

“This came before the loop, in the phone screen, which I wasn't really expecting.”

Amazon SDE Intern round that ran way over time, with a behavioral opener, a deep dive into a genAI project, and a meeting rooms coding problem that spiraled into multiple follow-ups. The candidate felt okay about the approach but is now spiraling about the time complexity mistake and whether starting with brute force hurt them.

Tell me about a time you worked on something and realized midway through that your approach wasn't working. What did you do?Walk me through your project in depth. Why does this approach work, and why wouldn't it have worked before now?You used a generative AI component in your project. How does it work, and why is it the right tool for this problem?+2 more

“Standard leadership-style opener, went through it fine I think.”

Jul 2026

Went through Amazon's HackOn OA for an SDE Intern role. There were two sections: a DSA problem and a dev problem. Cleared all test cases on the DSA side but only got 3 out of 6 on the dev section, so now I'm wondering if anyone actually cleared both and what stack they used.

What approach and tech stack did you use to pass all test cases in the HackOn dev section?

“Got 3/6 on the dev section and I'm still not sure if it was a logic issue or something about the stack I picked.”

Amazon·Software Engineer·Online Assessment (OA)

Rejected

Jul 2026

Took the Amazon SDE2 online assessment after six months of prep including neetcode 150 and a bunch of tagged questions, and still bombed it. The algorithm question looked like a graph problem but was actually a prefix sum variant, and I burned too much time going down the wrong path. Got rejected.

Given a coding problem with multiple failing test cases, identify and fix as many bugs as possible within the time limit.Solve an algorithm problem that involves computing range-based aggregations over a sequence, requiring recognition of an underlying prefix sum pattern beneath a layer of abstraction.

“This was the AI coding round.”

Amazon·Data Scientist·Technical Phone Screen

Jul 2026

SQL technical screen for a Data Scientist role at Amazon. One question, pretty focused, centered on window functions and how to pull first-per-group records out of an orders table.

Given an orders table with merchant IDs, order IDs, amounts, and dates, write a SQL query that returns each merchant's first order for every calendar date they had activity.

“I knew ROW_NUMBER() was the right move but fumbled for a second on whether to partition by just merchant_id or by both merchant_id and order_date.”
