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.
