harvey Interview Questions

This Harvey interview question requires designing a simplified spreadsheet application capable of storing both raw numeric data and dynamic formulas. The task tests your algorithmic thinking and graph traversal skills by challenging you to handle cell references while actively detecting and preventing circular dependencies. You must carefully manage state updates and dependency tracking within a structured object-oriented framework. To view the comprehensive problem statement and verified model solution, a paid subscription is required.

This interview challenge, recently asked at Harvey, requires candidates to build a lightweight, hierarchical data storage utility mimicking a directory-based filesystem. The exercise evaluates your ability to handle standard file lifecycle operations, implement historical snapshots for state versioning, and design validation logic to compare synchronization across multiple storage instances. You will need to carefully manage path strings and maintain structural integrity throughout modifications.
