Samsung·Product Manager·Onsite - Product Sense / Strategy

Jun 2026
Samsung interview that threw a classic estimation question at me, the kind where you either have a framework or you're just guessing out loud. One question, but it had enough moving parts to keep me busy for a while.
  • Estimate the number of laptops currently in this office. Walk through your assumptions step by step, covering employees on-site, laptops per employee (primary, secondary, dev/test), storage and IT loaner inventory, and visitors. Then sanity-check your number against headcount and discuss which assumptions move the answer the most.

“I started with headcount and immediately second-guessed myself on the on-site ratio.”

Got a coding question at Samsung for an ML Engineer role, classic dynamic programming stuff. Nothing too wild but the space optimization part is where they seem to actually care.
  • Given an array of non-negative integers representing money in each house on a street, find the maximum amount you can steal without robbing two adjacent houses.

“I knew this problem but still fumbled explaining the recurrence out loud.”

Samsung·Software Engineer·Online Assessment (OA)

Jun 2026
Samsung SWE interview, got a grid traversal problem that felt pretty standard but I still managed to overthink parts of it. Not much else to say about the round itself.
  • Given a 2D grid of '1's and '0's representing land and water, count the number of distinct islands, where an island is a group of horizontally or vertically connected land cells.

“I went with DFS and marked visited cells by flipping them to '0' in place.”

Samsung·Data Analyst·Technical Phone Screen

Jun 2026
Samsung data analyst interview with a single scenario-based case question about planning a parking lot for a Best Buy store. Pretty open-ended, which I didn't expect for a DA role. No coding, just structured thinking.
  • You're working at Best Buy and have been asked to plan a new parking lot for a specific store. What data would you collect to make decisions about its size, layout, and operating policies?

“I went straight to foot traffic and peak hours because that felt obvious, but I stalled a bit when trying to connect data sources to actual decisions.”

Samsung·Data Scientist·Technical Phone Screen

Jun 2026
Samsung Data Scientist interview with a fermi estimation question about laptop counts in a corporate office. Pretty classic back-of-envelope stuff but the details they wanted made it trickier than expected.
  • Roughly how many laptops are physically present in a typical corporate office at any given moment? Walk through your assumptions, clarify what you're counting as a laptop, and give both a point estimate and a reasonable range.

“I started with headcount and worked outward, which felt right, but I almost forgot about the hybrid work piece entirely.”

Samsung·Software Engineer·Onsite - Product Sense / Strategy

Jun 2026
Samsung interview focused entirely on data collection strategy for their e-commerce platform. One question, pretty open-ended, but it went deeper than I expected once we got into the weeds.
  • A customer just purchased a product on Samsung.com. What data could you collect about that buyer, and how would you go about collecting it?

“I started rattling off the obvious stuff: name, email, shipping address, payment method.”

Samsung ML Engineer interview that was basically a palindrome deep-dive. More algorithmic than I expected for an ML role, but they clearly wanted to see how you reason through edge cases and complexity constraints, not just whether you know the answer.
  • Given a string, return true if it reads the same forwards and backwards after stripping non-alphanumeric characters and ignoring case. Your solution must run in O(n) time and use O(1) extra space.
  • Modify your palindrome solution so it returns true if the string can become a palindrome by deleting at most one character.
  • How would you extend this solution to handle full Unicode, including combining marks and non-ASCII letters?
  • Write test cases for your palindrome solution and analyze the time and space complexity of each variant you implemented.

“Two pointers from both ends, skip non-alphanumeric chars, compare lowercased.”

Samsung·Product Manager·Onsite - Product Sense / Strategy

Jun 2026
Samsung PM interview with a single product design question. Pretty open-ended, which I wasn't fully ready for.
  • How would you design a smart picture frame?

“I fumbled the opening a bit because I jumped straight into features without clarifying who the user even is.”

Two rounds for a new-grad infra/backend SWE role at what sounds like a big semiconductor company. Resume walkthrough and API stuff in round one, then live coding on HackerRank plus an API design discussion in round two. Felt okay about both but now sitting at 10 days past the promised 5-7 business day window with nothing from the recruiter.
  • Walk us through your resume and relevant experience.
  • API design questions covering how you'd structure and expose backend services.
  • Live coding problem in a HackerRank environment (LeetCode-style algorithmic question).

“Pretty standard opener but I always underestimate how much they actually dig in.”

Samsung·Software Engineer·Hiring Manager Screen

Jul 2026
Went in for a mid-level software engineer interview and spent the whole thing getting lectured by a director of engineering who decided within the first two minutes that I was doing everything wrong. Less an interview, more a one-sided roast session I wasn't allowed to respond to.
  • What area of knowledge do you most want to develop over the next year?
  • Walk me through a technical problem you solved that you listed on your resume.

“Said system design, because I work with microservices but never really got visibility into the architectural decisions behind them.”
