Amazon·Software Engineer·Online Assessment (OA)

Jun 2026
Amazon SWE coding round, pretty much a standard scheduling problem. Nothing too wild but the input format tripped me up more than the actual algorithm.
  • Given a list of meeting time intervals, find the minimum number of conference rooms needed to hold all meetings without overlap.

“Classic interval scheduling problem.”

Amazon·Product Manager·Onsite - Product Sense / Strategy

Jun 2026
PM interview at Amazon with a product design question framed around a competitor scenario. Just the one question from what I can tell, but it had a lot of layers to unpack.
  • You're a PM at a quick-commerce grocery platform. How would you design and launch a new liquor delivery segment within the platform?

“I spent the first minute just thinking about how different this is from adding, say, a new snack category.”

Amazon·Software Engineer·Technical Phone Screen

Jun 2026
Amazon data engineer coding round, two problems back to back. The first was a warm-up and the second is where things got interesting. Complexity discussion was expected for both.
  • Given an array of words, convert each word to its Morse code representation by concatenating the Morse codes of its letters, then return the count of distinct translations across all words.
  • Given a string and a word dictionary, return all possible sentences formed by inserting spaces into the string such that every word in the sentence exists in the dictionary. Words can be reused.

“Pretty straightforward once you see it.”

Amazon·Software Engineer·Technical Phone Screen

Jun 2026
Amazon SWE interview with a coding round focused on interval merging. The problem had a clean surface but a bunch of edge cases that sneak up on you if you're not careful.
  • Given an unsorted list of integer ranges as half-open intervals [start, end), merge all overlapping or directly adjacent ranges and return the merged list sorted by start, along with the total length covered.

“Sorting by start was the obvious first move and I got there quickly.”

Amazon·Software Engineer·Recruiter / HR Screen

Jun 2026
Prepping for an Amazon software engineering role with a mountain of materials and a tight timeline. The recruiter made it clear the bar was high, which didn't exactly help with the anxiety.
  • You were handed an overwhelming amount of prep material with very little time. How did you figure out what actually mattered, prioritize your review, and push back on the recruiter without burning the relationship?

“I basically panicked for a day before realizing I couldn't cover everything and something had to give.”

Amazon·Product Manager·Onsite - Behavioral / Leadership

Jun 2026
Amazon PM behavioral round, pretty much what you'd expect from them. One question but it had some teeth to it.
  • Describe a situation where you pushed back on a customer request that you felt was unreasonable.

“This one's tricky because Amazon is all about customer obsession, so saying 'no' to a customer feels like you're walking into a trap.”

Amazon·Software Engineer·Technical Phone Screen

Jun 2026
Amazon SWE coding round, 40 minutes, one problem involving a circular array with multiple distance queries. Pretty focused session, no fluff.
  • Given a circular array of distances and multiple query segments, compute the total minimum distance across all queries.

“Looks like a bus stop shortest path problem at first glance but the multi-query angle changes things.”

Amazon·Software Engineer·Onsite - Behavioral / Leadership

Jun 2026
Amazon behavioral loop for a software engineering role. Pretty much all leadership principles stuff, they want you deep in the weeds on your projects and they will push back if your answers feel vague.
  • Walk me through your most impactful project: what were the goals, what was your specific role, what results did you drive, and what obstacles came up and how did you work through them?
  • Describe a situation where you pushed yourself outside your comfort zone. What made you decide to do it, what did you actually do, and what did you take away from it?
  • Tell me about a time you received critical feedback. What was the feedback, how did you react, and what happened afterward?

“This is the one I overprepared for and still fumbled parts of.”

Amazon·Software Engineer·Technical Phone Screen

Jun 2026
Amazon SWE coding round, pretty much one problem the whole time. Classic array question dressed up with a story about movies on a plane.
  • Given a flight duration (in minutes) and an array of movie lengths, find any two indices i and j where i != j such that the two movie durations add up exactly to the flight duration. Return an empty result if no such pair exists.

“It's two sum.”

Amazon·Research Scientist·Onsite - System Design / Architecture

Jun 2026
Amazon RS loop, ML system design focused on search ranking and experimentation. The round goes deep on a single axis rather than broad coverage, which I wasn't fully expecting. Generative variants with brand-fidelity checks made it more interesting than a standard ranking question.
  • Walk through how you would design a search ranking system end to end, from retrieval through re-ranking.
  • How would you evaluate generation quality for image or text outputs?
  • If an image is generated for a brand ad, how do you ensure the brand name appears correctly in the output?
  • How would you design an A/B test for a ranking change that avoids contamination from network effects?
  • How do you handle position bias when training a ranker on implicit user feedback?

“The key thing nobody tells you before these rounds: they don't want breadth, they want you to pick a layer and go five levels deep.”
