Software Engineer
Roblox · Mid-level
Prepare for the Roblox Software Engineer interview with 4 practice rounds and what each one looks for. Pick any round and an AI interviewer runs it with you at full length, with follow-up questions. Afterwards you’ll see what went well and what to work on next.
Your first 60 minutes of practice are free. No card needed.
Next: your first full round
Do the Online assessment: coding and games round.
One full practice round shows where you stand before you work on anything specific.
The rounds
Pick a round to see what it asks of you and where you stand on it.
Online assessment: coding and games
See whether you can solve hard algorithm problems and optimization tasks on your own, under time pressure, when the instructions aren't fully clear.

What strong sounds like
- Names a correct approach for the problem type and explains why it beats the brute-force option.
- Code as written handles the main case. A manual dry-run on a sample input confirms the output.
- Moves on from a stuck task, returns later, and leaves a usable partial solution for each task.
Expect to be pushed on
Asks for a faster approach after a working but slow solution.
Shapes of problem you may get
- Hard graph, matrix, or dynamic programming problem, sometimes with a Roblox-style product twist
- Game-style task that needs a rule inferred and then an optimized strategy
How to prepare
What they look for
Roblox doesn't publish its software engineer interview process. Guides and candidate reports describe an online assessment that mixes coding problems with Roblox-hosted strategy games, then one or two 45-minute coding interviews, behavioral interviews, and a hiring manager chat. One 2025 report pairs an algorithm interview with an object-oriented design interview. Guides list system design for experienced candidates, but no report confirms how a mid-level loop handles it, and the round count and order still vary.
They reward
- Clear reasoning that you share as you solve problems
- Correct, efficient code with edge cases checked
- Specific stories that show your own decisions and results
- Staying calm when instructions are unclear
What to avoid
- Don't spend most of your time on one problem.
- Don't skip the complexity check for large inputs.
- Don't start coding before you and the interviewer agree on the approach.
- Don't brush past a hint from the interviewer.
- Don't add classes you can't explain a need for.
How sure we are
Worth redoing if you hear something from the recruiter that contradicts this.
