The Roblox OA is the online assessment Roblox sends early career applicants, such as interns and new grads, and Roblox calls it "your first interview": it replaces the resume review. It mixes game-based problem-solving tasks built on Roblox (Robots and Factories), workplace scenarios that test how you make decisions, and, for technical applicants, a coding evaluation and an algorithmic reasoning assessment. Roblox's coding assessment includes a block-coding task called Outpost: Mars. You can do every part at once or spread them over a week, and two free, untimed practice games, Kaiju Cats and Coding Cookies, teach the controls. Roblox's careers page has said the typed coding test is sent through CodeSignal, and candidates report 2 coding problems in about 50 minutes.
From Roblox's own hiring pages and the test platform's help pages, checked November 3, 2026. Anything that comes from candidate reports says so. Your invitation email wins if it says something different.

Roblox says it uses a mix of assessments that measure problem solving, technical ability and decision making, and that required assessments vary by role. These are the parts it describes, in our own words.
Game tasks built on Roblox where you plan, test and adjust a solution, such as building a machine that can cross rough ground or reworking a production line so it stops backing up.
Tip: Play Kaiju Cats first. Roblox says it mirrors the controls and tactics you will meet in Robots and Factories.
Roblox has said you may explain the methods you used after the games, and a Roblox engineer says you will be asked to articulate your strategy.
Tip: Note your plan and why you changed it as you play, so your explanation is quick and specific.
Short work situations, such as a deadline at risk or a blocker from another team, where you choose the most and least effective response.
Tip: Look for the response that raises problems early and keeps the right people informed, not the one that hides the issue.
A coding task in a block-based editor instead of typed code. Candidates report building small reusable functions during a testing phase and calling them later.
Tip: Play Coding Cookies until the block editor feels natural. It is untimed and nothing there is scored.
A coding evaluation unique to Roblox, sent through CodeSignal. Candidates report 2 problems in about 50 minutes.
Tip: Submit a working solution early, then improve it. On CodeSignal you only get credit for work you submit.
Roblox lists an assessment on algorithmic reasoning next to the coding evaluation for technical applicants, without describing its format publicly.
Tip: Practice tracing what a short algorithm does, step by step, by hand before you run anything.
Roblox says "there isn't one single dimension upon which we measure performance" and that there is not always one right way to solve a problem. In Roblox's own article, an early career engineer advises: "Roblox looks at your performance as a whole, so take short breaks between sections."
Roblox publishes no passing score. After you finish, it says you will hear back within a few weeks while it calibrates the assessments, and everyone who passes gets to interview with the team. The next stage is a set of virtual onsite interviews.
The coding test is unique to Roblox, not CodeSignal's standard General Coding Assessment, and candidates report that earlier CodeSignal scores cannot be reused for it. CodeSignal's custom tests usually do not show you your score.
Roblox's free practice game mirrors the controls and tactics of the Robots and Factories tasks. It is replayable and untimed, and your play there does not affect your results.
It teaches the block-coding editor you will meet in Outpost: Mars. Nothing in it is scored, so experiment until building with blocks feels natural.
Candidates report 2 coding problems in about 50 minutes. Do CodeSignal's free practice assessments to get used to the editor; companies cannot see your practice activity.
Roblox lets you take everything at once or spread it over a week, and you can ask for an extension. Take short breaks between sections, and use Speak_ for guides and live workshops.
Roblox does not publish how it proctors its assessment. One candidate in the 2027 intern and new grad cycle described the CodeSignal coding round as unproctored. The setup screen of each part tells you what is recorded.
On CodeSignal, employers can see a Suspicion Score for each coding question, built from signals like code similarity, pasting, copying the question text and session replay.
Not in a form that helps much. Roblox says there is no single right way through its problem-solving games and that it looks at your approach, the workplace scenarios have no answer key, and the coding test is unique to Roblox, with hidden test cases deciding the score. For the typed coding problems, Coding Copilot reads the exact problem on your screen and gives you an approach, a dry run and working code for it.
On the typed coding part, OphyAI Coding Copilot works: one hotkey reads the problem on your screen, and the approach, complexity notes and working code appear in an overlay that screen sharing and recording leave out. In the virtual onsite interviews, Space or Cmd/Ctrl + Shift + L transcribes the question your interviewer asks out loud. It is not built for the games, the block-coding task or the workplace scenarios.
Roblox does not publish how it checks integrity. On CodeSignal, employers can see a Suspicion Score for each coding question built from code similarity, pasting, copying the question text and session replay. The OphyAI window is hidden from screen sharing and recording, but not from a webcam, a person watching, or the platform's own keystroke, paste and tab tracking.
Compare every platform: Can online assessments detect AI?
Coding Copilot in the OphyAI desktop app reads the coding problem on your screen with one hotkey and returns an approach, complexity notes and working code in your language.
Use OphyAI Coding Copilot on the typed coding part of your real Roblox OA, not just to practice. Press Cmd/Ctrl + Shift + A and it snaps the problem window, even when other windows cover it, or press Cmd/Ctrl + Shift + S to drag a box around just the problem. The answer appears as a card in a floating overlay that macOS and Windows leave out of screen sharing and recording: how OphyAI read the problem, the code with line numbers, a dry run with edge cases, and the Big O. In the virtual onsite interviews, press Space or Cmd/Ctrl + Shift + L and it transcribes the question your interviewer asks out loud.
Most of the Roblox OA is not a fit for OphyAI. The Robots and Factories games and the Outpost: Mars block-coding task are interactive games, and the workplace scenarios ask for judgment calls with no single right answer. Aptitude Test mode answers multiple-choice questions with one right answer, so it is not built for any of these. Practice them with Kaiju Cats and Coding Cookies instead.
On the typed coding part, CodeSignal shows employers a Suspicion Score for each submission.
Cmd/Ctrl + Shift + A snaps the problem window, even when other windows cover it, and Cmd/Ctrl + Shift + S lets you drag a box around part of the screen. In a live interview, Space or Cmd/Ctrl + Shift + L transcribes the question the interviewer asks out loud.
Answers show as a card in a floating overlay that macOS and Windows leave out of screen sharing and recording. It stays on top of a full-screen editor or browser and opens without taking the keyboard from your editor.
Each answer card shows how OphyAI read the problem, what to say first, the code with line numbers, a dry run with edge cases, and the Big O. Follow-ups remember the problem, so "now handle duplicates" updates the same code.

Hiding a window from screen share does not hide it from a webcam, a person watching, keystroke and paste history, tab or focus tracking, or proctoring software.
Roblox does not publish a total time. It lets you take every part at once or spread them over a week. Candidates report the typed coding part alone is 2 problems in about 50 minutes.
The typed coding test is. Roblox's careers page said through May 2026 that it is "sent to all technical applicants via CodeSignal," and a 2026 candidate reports a CodeSignal round. The games and workplace scenarios run inside Roblox.
Play Kaiju Cats for the problem-solving games and Coding Cookies for the Outpost: Mars block editor; both are free, untimed and not scored. For typed coding, use CodeSignal's free practice assessments, and sign up for Speak_ for Roblox's guides and workshops.
Yes. Roblox says you can request an extension by submitting a ticket, and questions about the assessments go to assessments-support@roblox.com.
Candidates report that you cannot. Roblox says its coding test is unique to Roblox, so it is not CodeSignal's standard General Coding Assessment, whose verified scores can be shared.
Within a few weeks, Roblox says. It uses that time to calibrate the assessments before following up with next steps.
Roblox says everyone who passes gets to interview with the team. The next stage is a set of virtual onsite interviews, and Speak_ has courses and live workshops that cover them.
