- Hat Assignments in an Early-Career OnsiteRoblox · Software Engineer · Onsite · Sep 2026
The author reports two coding interviews during a Roblox early-career virtual onsite. One problem asked for the number of valid hat assignments and the highest score obtainable when hats carry point values. The author considered dynamic programming or backtracking, noting that the smaller input size might permit the latter. The second problem was identified only as a Candy Crush exercise, without…
- 2027 Intern/New Grad OA Games and CodingRoblox · Software Engineer · Online Assessment · Aug 2026
My Roblox OA from a month ago. Round 1: Cognitive Games, three mini-games Robots: Assemble tools to cross different terrain. Try different assemblies to reach the finish. Factory: Optimize the production-line network, identify bottleneck stations, and maximize cash flow on the high-profit lines. Mars: Outpost: Modular programming. Watch out: only functions packaged during the testing phase can be…
- A Shared To-Do List Design and a Kafka MistakeRoblox · Software Engineer · Technical Screen · Aug 2026Rejected
The system design question was the shared to-do list problem from the question bank. Unfortunately, I had not had time to prepare for it. This was also my first system design interview, so I did not perform very well. I made one critical mistake by adding a Kafka queue. That made the system asynchronous and would affect the speed of the synchronous flow. The interviewer still interacted with me t…
- Phone Screen Piano Keys Coding ChallengeRoblox · Frontend Engineer · Senior+ · Technical Screen · Aug 2026
Phone Interview Coding/design question: Piano Keys Implement a UI with 6 piano keys (C, D, E, F, G, A) that responds to user input. Must be built with vanilla HTML/CSS/JavaScript only — no frameworks or third-party libraries. When a key is pressed and held, it should show a pressed state (i.e., add the pre-styled .key.active class to the corresponding element); when released, it should immediatel…
- Puzzle-Game Assessment, Then a Match-3 and Autocomplete Phone ScreenRoblox · Software Engineer · Technical Screen · Aug 2026In progress
Sharing my Roblox interview experience, hoping it helps everyone. I'm still in the middle of interviewing right now. I applied to Roblox with three years of full-time experience, mass-applying as an experienced hire. I don't know why, but they first gave me an online assessment, which is mostly playing their little puzzle games plus answering some behavioral questions. I have to complain about th…
- A Robot Navigating a Laser-Covered GridRoblox · Software Engineer · Online Assessment · Jul 2026
The interview experience was good overall, and the interviewer was very friendly. This time I got a classic grid graph search/simulation question. The problem statement was quite long and needed careful reading. The original question follows: Problem description: Imagine a board of size numRows × numColumns with some lasers on it. These lasers are located in the two-dimensional array laserCoordin…
- Roblox Software Engineer interview: challenging but relaxed SuperdayRoblox · Software Engineer · Online Assessment · Jul 2026
After applying online, I took an online assessment built around game-style problem solving. The Superday itself was tough, though most interviewers were laid back and friendly. The technical side leaned heavily on numerous LeetCode-style questions in the medium-to-hard range. The behavioral questions were not just warmups. They were difficult enough that I had to be specific about how I would han…
- Nailed the Case Study, Still Rejected After Round OneRoblox · Data Scientist · Technical Screen · Jan 2026Rejected
(QS 50-100 school, physics PhD, desperately job hunting.) First round, technical interview, 60 minutes. The interviewer asked about my resume for 5 to 10 minutes first (my own work also has some connection to DS). Then two simple pandas data-processing questions using a bit of basic statistical test knowledge. I didn't need to run test cases, I just had to make the interviewer understand my code.…
- A Brutal OA With Robot-Building and Factory GamesRoblox · Data Scientist · Online Assessment · Nov 2025
First-time poster here. After I got the OA, I asked the career center for an extension but didn't get one, so I ended up squeezing it into one evening of Thanksgiving break, a week before finals deadlines. After I finished I felt like my English was terrible and my IQ had dropped :((( It seriously wrecked my mood for the rest of finals prep. 25 minutes building a robot car. There were two rounds…
- A Four-Part OA With Two In-Platform GamesRoblox · Data Scientist · Intern · Online Assessment · Nov 2025
Roblox's DS summer intern OA has 4 parts: the first two parts are both playing games on Roblox's own platform, the third part is basically behavioral multiple choice, and the fourth part is coding. Part 1: a build-a-car game, 25 minutes total; 2 sections, 13 minutes each, and each section has two different terrains. You need to install different parts on a car to get through both terrains, and th…
- Python, SQL, and Rejection at the Hiring Manager RoundRoblox · Data Scientist · Senior+ · Technical Screen · Nov 2025Rejected
I applied online among lots of other applications, and HR reached out afterward. The overall process was HR screen → technical → HM. I failed at the HM round and didn't make it to the onsite. The HR phone screen was fairly standard, mainly asking: Self-introduction. Why are you leaving? Why Roblox? What are you looking for in your next role? The technical interview lasted an hour and mainly cover…
- A Four-Part OA With Two Weird Simulation GamesRoblox · Data Scientist · Intern · Online Assessment · Oct 2025
Roblox's DS summer intern OA has 4 parts: the first two parts are games played on Roblox's own platform, the third part is basically behavioral multiple choice, and the fourth part is coding. Part 1: the car-building game, 25 minutes total; 2 sections, 13 minutes each, and each section has two different terrains. You need to equip a car with different parts to get it through both terrains, and th…
- An Onsite Derailed by a Disrespectful PMRoblox · Data Scientist · Onsite · Oct 2025
Roblox is a really hot pre-IPO unicorn, and lately they're hiring a lot, so a lot of candidates are interviewing there. I get it, a lot of people want in, but I have to complain a bit — the experience was, if anything, worse than others I've seen on this board. After the IPO the stock will probably pop, but long-term it's genuinely hard to say. Phone screen 1: HM The hiring manager was pretty nic…
- Gamified Assessment and a Meta-Style Product Sense Case, No OfferRoblox · Data Scientist · Intern · Onsite · Oct 2025Rejected
This application season I applied for Roblox's PhD DS Summer Intern position. I didn't end up passing, but I felt the team's overall background was pretty solid, and the assessment was a bit different from the usual, so I wanted to share it here. Timeline: 11/23/2024 — applied online, got the assessment the same day 12/19/2024 — submitted the assessment 02/12/2025 — HR reached out 02/27/2025 — vi…
- One Technical Screen, a Rare Trie/Heap Question, No OfferRoblox · Software Engineer · Technical Screen · Oct 2025Rejected
A bit unlucky — I ran into an interviewer for this round. At first I was pretty happy, thinking we might have something in common, but then I got the lowest-frequency, hardest question in the database, and I didn't finish it. I ended up failing. I'm not sure whether it was because of the coding, or my resume, or maybe just because I didn't finish the coding — either way, my feedback didn't stack…
- Digit-Grid Phone Screen, Then Resource Loader and Pub/Sub System Design OnsiteRoblox · Software Engineer · Onsite · Sep 2025In progress
Engine-related role — all the questions were things I'd never seen anywhere on this forum before. Phone Screen: Phase 1 was an m*n grid where each cell holds a digit from 0-9. I had to collect every horizontal or vertical run of 3 or more matching digits and record each one in a results array, in the format [position, length], with the results ordered top-to-bottom and left-to-right. Phase 2 buil…
