Got through both problems but fumbled an edge case on the second one.
Acknowledge the missed edge case directly and walk through how you would systematically identify and handle edge cases in similar problems. Emphasize your process for testing and validating solutions, showing that you learn from the experience.
Pro tip: Demonstrate that you now proactively enumerate edge cases before coding, and mention that you keep a personal checklist of common edge cases (e.g., empty input, single element, duplicates, overflow) to prevent similar misses.
Briefly admit that you missed an edge case without making excuses, showing self-awareness and accountability.
Describe what the edge case was, why it matters, and how it could affect the solution's correctness or performance.
Share a structured method you use to identify edge cases, such as categorizing by input size, data types, and problem constraints.
Explain the steps you would take to modify the solution and verify it with targeted test cases, including the missed edge case.
Summarize how this experience improved your problem-solving process and how you apply these lessons in future coding.
