Amazon·Product Manager·Hiring Manager Screen

May 2026
Interviewed for a PM role at Amazon, got asked a people-focused question that felt more like a leadership gut-check than anything product-related.
  • Who is the best employee or resource you've worked with, and what specifically made them stand out?

“I rambled a bit here.”

Amazon·Software Engineer·Online Assessment (OA)

May 2026
Amazon SWE online assessment with two algorithmic problems. Neither was straightforward and the second one in particular had some tricky edge cases around the constraint logic that I didn't fully work through in time.
  • You're given an integer array. Repeatedly find the smallest undeleted element (leftmost if tied), add it to a running total, then delete it along with its immediate original-array neighbors if they haven't been deleted yet. Return the total after all elements are gone.
  • A warehouse starts empty with a fixed max capacity. Each day its inventory changes by a given amount. Before any day you can do an emergency refill up to the capacity limit. Days where the change is zero require non-negative inventory at day's end; other days can temporarily go negative. Find the minimum number of refill days needed, or return -1 if it's impossible.

“The leftmost-on-tie rule tripped me up more than I expected.”

Amazon·Software Engineer·Online Assessment (OA)

May 2026
Amazon coding round for a Software Engineer position, two algorithm questions back to back. Pretty standard stuff if you've been grinding leetcode, but the pressure of doing it live is a different thing entirely.
  • Given the root of a binary tree and two distinct nodes p and q that both exist in the tree, find and return their lowest common ancestor. A node can be its own ancestor.
  • You're given an array where each element represents the money in a house. You can't rob two houses that are next to each other. What's the maximum amount you can collect?

“Classic tree problem and I still fumbled the base case for a second.”

Amazon·Product Manager·Onsite - Product Sense / Strategy

May 2026
Amazon PM interview with a single system design question about building Alexa from scratch. Not a lot of context to go off of, but it's the kind of open-ended product design prompt that can spiral in a dozen directions if you're not careful.
  • How would you design Alexa as a product?

“This is the kind of question where you can either go broad and shallow or pick a lane and actually say something interesting.”

Amazon·Software Engineer·Online Assessment (OA)

May 2026
Amazon SWE online assessment, one coding problem about simulating a parcel sorting process. Pretty straightforward simulation but the phrasing threw me off at first.
  • Given a permutation array representing a sorting sequence, find the minimum number of full passes required to process all elements in order (where each pass goes left to right and arranges any element that matches the next expected value).

“The problem description is wrapped in this warehouse/parcel story which honestly made it harder to parse than the actual logic.”

Amazon·Software Engineer·Technical Phone Screen

May 2026
Amazon SWE interview with a deep-dive question on generative AI work. Just the one question but it had a lot of surface area to cover.
  • Walk me through a generative AI or LLM project you worked on. What was the problem, what design and modeling decisions did you make, and what trade-offs around cost, latency, hallucination, and evaluation did you run into? What was the measurable impact?

“This question is deceptively wide.”

Amazon·Software Engineer·Onsite - System Design / Architecture

May 2026
Amazon SWE system design round, one big open-ended question about robot navigation and human avoidance. No fluff, just a deep technical dive that took the whole session.
  • Design a mobile robot navigation system for an indoor/warehouse environment that can safely avoid humans while moving toward a goal. Cover sensor selection, core data structures, system architecture with module breakdown, planning strategy for dynamic obstacles, and write pseudocode for a main control loop.

“This was a beast of a question.”

Amazon·Product Manager·Onsite - Behavioral / Leadership

May 2026
Went through a PM interview loop at Amazon. Mix of behavioral and career questions, nothing too surprising but the ambiguity one caught me thinking harder than I expected.
  • Why do you want to work at Amazon?
  • What draws you to this Product Manager role specifically?
  • Tell me about a time you were in the middle of a project and had to change course. What happened and what was the outcome?
  • Describe a situation where you had to act quickly with incomplete or unclear information. How did you handle it?
  • Where do you see yourself professionally in the next five years?

“Prepared this one but still felt like I was reciting a script.”

Amazon·Software Engineer·Onsite - Product Sense / Strategy

May 2026
Amazon interview for what seemed like a marketing or product role tied to Twitch Prime partnerships. Single question, pretty open-ended, not much else to go on.
  • How would you promote Borderlands 3 to Twitch Prime subscribers?

“This is the kind of question where you can go a dozen directions and none of them feel obviously wrong, which is almost worse than a hard constraint.”

Amazon·Software Engineer·Technical Phone Screen

May 2026
Amazon SWE interview with a coding round focused on board validation. Pretty algorithmic, no behavioral stuff from what I can tell. The problem had some depth to it once you got past the surface.
  • Given a partially filled 9x9 Sudoku board with digits '1'–'9' and '.' for empty cells, write an algorithm to check whether the current state is valid. No duplicates allowed in any row, column, or 3x3 sub-box. They also asked you to do it in a single pass and explain your data structures and complexity.

“The single-pass constraint is what makes this interesting.”
