This part went fine, maybe the best part of the whole process.
Select 2-3 projects that best demonstrate your end-to-end ownership, technical depth, and impact, and structure your walkthrough around the problems they solved rather than a chronological list. For each, briefly describe the game, your specific role, the key technical challenges, and the measurable outcomes, tying them to skills relevant to Roblox's platform and scale.
Pro tip: Emphasize how you iterated based on player feedback or metrics, and be ready to discuss what you would do differently—this shows product sense and adaptability, which are critical at Roblox.
Briefly introduce your portfolio's scope and the criteria you used to select the projects you'll discuss, signaling intentionality and relevance to the role.
For each project, state the game's genre, target platform, team size, and your specific role, then summarize the core gameplay loop in one sentence.
Highlight 1-2 technical challenges you solved, explaining your approach, trade-offs, and the technologies or systems you built or integrated.
Quantify the project's success using metrics like DAU, retention, revenue, or performance improvements, and mention any awards or notable recognition.
Share key lessons learned, how you adapted to setbacks or ambiguity, and how those lessons apply to building on Roblox's platform.
AI-generated suggestions, not part of the candidate's original notes. May be inaccurate — verify before relying on them.
Start by clarifying the problem, constraints, and edge cases, then propose a brute-force solution before optimizing. Implement the optimal solution with clean code, test it thoroughly, and then adapt it to the follow-up variant by identifying what changes and how to extend your approach.
Pro tip: Verbalize your thought process and trade-offs continuously, as interviewers assess problem-solving and communication as much as coding. When handling the follow-up, explicitly connect it to the original problem to show adaptability.
Ask questions to understand the problem, input/output, constraints, and edge cases. Confirm assumptions with the interviewer before proceeding.
Discuss a brute-force solution and its complexity, then propose optimizations using appropriate data structures or algorithms. Compare trade-offs.
Write clean, modular code for the chosen approach. Walk through examples and test edge cases to verify correctness.
State the time and space complexity of your solution and discuss potential improvements or alternative trade-offs.
Listen carefully to the variant, identify how it differs, and adapt your solution. Explain the changes and re-analyze complexity.

Use the STAR method to structure your answers, focusing on specific situations where you navigated ambiguity or resolved conflicts. Highlight your thought process, actions, and measurable outcomes, and connect them to Roblox's engineering culture and values.
Pro tip: Quantify your impact whenever possible (e.g., 'reduced deployment time by 30%') and show how you turned ambiguity into a structured plan. Roblox values engineers who can drive clarity and collaborate effectively.
Briefly describe the situation, including the project, team dynamics, and why it was ambiguous or conflicted. Keep it concise to leave time for your actions.
Detail the steps you took to understand the problem, gather information, and align stakeholders. Emphasize how you brought clarity or resolved tension.
Describe how you worked with others, communicated effectively, and adapted to changing circumstances. Show empathy and active listening.
Conclude with the results: what was achieved, what you learned, and how it impacted the team or product. Use metrics if possible.
Briefly reflect on what you would do differently or how the experience prepared you for similar challenges at Roblox. Tie back to the role.
