Company: Anthropic
Role: Software Engineer
Category: Coding & Algorithms
Difficulty: medium
Interview Round: Onsite
Quick Answer: This question evaluates a candidate's ability to combine bitmasking with backtracking or subset enumeration to maximize a constraint over combinations of strings. It tests practical application of state-space search and character-set tracking, a common category in coding interviews assessing algorithmic problem-solving under small input bounds.
