AI in interviews
No public policy found. Assume no AI assistance in live rounds unless your recruiter says otherwise.
Typical interview loop
How Roblox usually runs it for applied AI and LLM engineer roles.
- Focus: Background, motivation
Talent acquisition intro call
A recruiter conversation about your background, why Roblox, and where you want your career to go.
- Focus: Coding, systems thinking
Technical skills assessment
Usually an online coding assessment, which can include game-style problem-solving simulations; senior roles may get a design exercise or take-home instead.
- Focus: Coding, design, project depth
Technical rounds
Back-to-back sessions mixing live coding, object-oriented or system design, and a deep review of a past project.
- Focus: Values, structured problem-solving
Behavioral and values interviews
Conversations with teammates and leaders, including an open-ended problem-solving interview that tests how you frame an ambiguous problem rather than a technical answer.
- Focus: Team fit
Hiring manager chat
A closing conversation with the prospective manager about fit and motivation.
- Focus: Final calibration
Hiring committee review
Not an interview: senior engineering leaders review your packet of interviewer feedback and the manager's summary to decide.
