Algorithm Selection and Justification Questions

Evaluates the ability to choose and justify algorithms and approaches for solving computational problems. Topics include analyzing time and space complexity, selecting data structures, comparing exact versus approximate or heuristic solutions, considering parallelization and streaming approaches, caching and memoization strategies, and balancing correctness versus performance and maintainability. Interviewers expect candidates to define constraints clearly, compare alternatives, and explain why the chosen algorithm best fits latency, throughput, memory, and operational requirements.
