Find Minimum Compatible Version
Company: OpenAI
Role: Machine Learning Engineer
Category: Coding & Algorithms
Difficulty: medium
Interview Round: Onsite
Quick Answer: This question evaluates binary search, monotonic predicates, careful version ordering, and cost-aware optimization of expensive compatibility checks. It is commonly asked in the Coding & Algorithms domain to test reasoning about monotonicity, minimizing API calls, and adapting search strategies when monotonicity holds only within subranges; the level of abstraction combines conceptual understanding of monotone properties with practical application of efficient search techniques.
