Find most frequent call path in logs
Company: Roblox
Role: Software Engineer
Category: Coding & Algorithms
Difficulty: medium
Interview Round: Technical Screen
Quick Answer: This question evaluates stack-based simulation of single-threaded call traces, hierarchical path construction and frequency counting with deterministic tie-breaking by depth and first occurrence. It is commonly asked in the Coding & Algorithms domain to assess practical application of data structures and parsing logic for runtime logs rather than purely conceptual theory.
