Got 11/15 on q1 due to TLE and now just sitting here refreshing my inbox.
Acknowledge that you don't have the exact question, but explain that the scenario is common in Amazon OA (e.g., a problem requiring an optimized algorithm). Focus on how you would handle a time limit error: analyze complexity, identify bottlenecks, and optimize. Then address the advancement question by noting that Amazon typically considers overall performance, not just one test case, and that many candidates advance with partial scores.
Pro tip: Emphasize that Amazon values problem-solving and optimization skills over perfect scores; showing how you would debug and improve a solution is more impressive than knowing the exact question.
State that without the exact problem statement, you can't specify the question, but you can discuss the typical pattern of OA problems that cause time limit errors.
Explain that passing 11/15 test cases suggests the solution is correct but inefficient; the failing cases likely involve larger inputs or edge cases.
Discuss common optimizations: improving time complexity (e.g., from O(n^2) to O(n log n)), using efficient data structures, or avoiding redundant computations.
Explain that Amazon's hiring decision is holistic; a partial score can still lead to advancement if other sections (e.g., work simulation, logical reasoning) are strong.
Summarize how you would approach similar problems in the future: test with large inputs, analyze complexity early, and practice optimization techniques.
