Came up with something the interviewer hadn't considered.
Start by clarifying the problem and constraints, then present your solution with clear reasoning about time/space complexity and trade-offs. If the interviewer has a different solution in mind, acknowledge their approach, compare it objectively, and defend yours with data or edge cases, while remaining open to feedback.
Pro tip: Treat the interviewer as a collaborator, not an adversary—frame differences as opportunities to explore trade-offs, and show you can disagree without being disagreeable.
Ask questions to ensure you understand the problem, constraints, and evaluation criteria. Confirm assumptions before diving into a solution.
Explain your approach step-by-step, including data structures, algorithms, and complexity analysis. Highlight why you chose this approach.
If the interviewer suggests a different solution, listen carefully, then compare both approaches objectively on correctness, efficiency, and readability.
Use concrete examples, edge cases, or complexity analysis to justify your approach. If the interviewer's solution is better, acknowledge it gracefully.
Be open to modifying your solution or combining ideas. Show flexibility and a focus on the best outcome for the problem.

Derived the whole thing myself, implemented it correctly on the first pass, then completely botched how I was appending the result.
Start by clarifying the problem and constraints, then walk through a simple example to understand the expected behavior. Develop a brute-force solution first, then optimize it by identifying patterns or using appropriate data structures. Finally, implement the solution while systematically testing edge cases and explaining your reasoning throughout.
Pro tip: Communicate your thought process clearly and involve the interviewer by asking clarifying questions and discussing trade-offs. This demonstrates collaboration and problem-solving skills, which are highly valued at Roblox.
Restate the problem in your own words and ask clarifying questions about input/output, constraints, and edge cases. Confirm your understanding with the interviewer before proceeding.
Walk through a few concrete examples, including simple and edge cases, to identify patterns and validate your understanding. Discuss potential pitfalls.
Propose a brute-force solution first, then analyze its time and space complexity. Optimize by choosing appropriate data structures or algorithms, explaining trade-offs.
Write clean, modular code with meaningful variable names. Test with the examples from step 2, and explicitly handle edge cases like empty inputs, large values, or duplicates.
Review your code for correctness and efficiency. Discuss potential improvements or alternative approaches, and ensure all edge cases are covered.

Use the STAR method to structure your answer, focusing on a specific situation where you navigated ambiguity and adapted to changing requirements. Emphasize your thought process, actions, and the positive outcome, while tying it back to the role and Roblox's values.
Pro tip: Show self-awareness by acknowledging what you learned from the experience and how you would approach a similar situation differently next time. This demonstrates growth and maturity.
Briefly describe the situation, including the project, team, and the ambiguous or changing circumstances. Be specific about why it was ambiguous.
Explain the specific challenge or problem you faced due to the ambiguity, and why it was important to address.
Detail the steps you took to adapt, such as gathering information, making assumptions, communicating with stakeholders, or iterating on solutions.
Share the results of your actions, including any metrics or feedback, and how it benefited the project or team.
Summarize what you learned and how it has prepared you for similar challenges at Roblox, aligning with the company's values.
