11 Software Engineer interview notes

Samsung·Software Engineer·Onsite - Multi Round

Sep 2026
Interviewed for a staff-level internal dev platform role at a hardware company you'd definitely recognize. The take-home went sideways because I tried to do more than asked, shipped a failing test, and then had to debug it live in front of five people at 7AM. It did not go well.
  • Given a working codebase as a take-home, implement one of two specified changes (with tests passing).
  • Build a REST API for a reservation system from scratch, including tests, within one hour.
  • System design interview round (details not specified).

“I decided to do both options instead of one.”

Samsung·Software Engineer·Hiring Manager Screen

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.”

Jul 2026
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·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·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 coding screen, basically just the classic islands problem. Nothing fancy, no behavioral, straight into the algorithm.
  • Given a binary grid of 1s and 0s, count the number of islands, where an island is a group of adjacent land cells connected in four directions.

“Classic problem, knew it cold.”

Jun 2026
Samsung SWE interview with a tree/graph problem that had a bit of a twist to it. Not the hardest question on paper but the constraint they added made me rethink my whole approach mid-answer.
  • How would you implement a parent-child relationship to find the Least Common Ancestor (LCA) of a tree without using pointers?

“I went straight to the classic recursive LCA approach and then realized mid-explanation that pointers were off the table.”

May 2026
Samsung Research Engineer interview had a long resume deep-dive section, roughly half an hour, with the interviewer jumping in constantly to probe design decisions and individual contributions. Be ready to defend every number you claim.
  • Walk me through your resume and past projects in detail.
  • Why did you make that specific technical or design choice in this project?
  • What was your individual contribution versus what the team did together?
  • What was the actual impact of this project and what metrics support that?
  • What did you learn from this project and what would you do differently?

“This ran way longer than I expected.”

Samsung·Software Engineer·Onsite - Behavioral / Leadership

May 2026
Behavioral round at Samsung, pretty open and conversational. Three big questions covering background, strengths, and a real weakness. Nothing tricky, just a lot of talking about yourself for an hour.
  • Walk me through your background: education, key roles, and what shaped your career path.
  • What are your top strengths, and can you give a concrete example of each one in action?
  • What is a genuine weakness you have, and what are you actually doing to work on it?

“I always fumble this one because I try to cover everything and end up rambling.”

Samsung·Software Engineer·Technical Phone Screen

May 2026
Technical phone screen for a robotics engineer role, focused on a coding problem with an embedded systems twist. Needed hints to get to the right answer on the embedded part, which was a bit embarrassing but at least I got there.
  • Implement a solution to find the maximum area of an island (similar to LeetCode 695), but optimized for embedded systems constraints. What changes would you make to the standard approach?

“The base algorithm I knew fine, BFS or DFS on a grid, no problem.”
