The "Task Management System" problem is a common technical interview prompt at companies like Anthropic, typically used to assess your ability to build functional systems from the ground up while handling real-world complexity and edge cases.
Problem Statement Overview
The core objective is to implement a system that can manage a collection of tasks and their associated states. While the prompt sounds simple, the interview focuses on incremental complexity—starting with basic CRUD (Create, Read, Update, Delete) and moving into multi-level logic.
Typical Requirements
Core Logic: Create tasks with attributes like ID, Name, Description, and Status (e.g., TODO, IN_PROGRESS, DONE).
State Management: Move tasks between statuses while ensuring logical transitions (e.g., you can't move a task to "Done" before it's "In Progress").
Advanced Features (The "Anthropic Twist"): 5
Sub-tasks/Dependencies: Handle hierarchical tasks where a "Parent" task cannot be completed until all "Child" tasks are finished.
Time Tracking: Track hours spent per task or employee, often including promotion or salary calculation logic based on hours worked Glassdoor.
Concurrency: Ensuring the system handles multiple users or processes updating the same task without race conditions Glassdoor.
Key Evaluation Criteria
Anthropic interviewers often look for structured reasoning and incremental development rather than just a final solution Exponent +1. 07
Code Quality: Use clear naming conventions and modular functions.
Incremental Testing: Show how you debug as you go. Many candidates succeed by running tests for each "level" of the problem before moving to the next Glassdoor.
Trade-offs: Be ready to discuss why you chose a specific data structure (e.g., a HashMap for 𝑂(1) lookup vs. a Tree for hierarchy) and how it affects performance.
Ambiguity Handling: Since their questions are often novel or based on internal problems, you are expected to clarify requirements and define "must-haves" versus "nice-to-haves" early on Exponent +1.
How to Prepare
Practice on Platforms: Use sites like LeetCode or CodeSignal to sharpen your speed, but focus on building full classes rather than just algorithms Glassdoor +1.
System Design focus: For senior roles, expect to discuss how this system scales to handle millions of tasks or optimizes database usage (e.g., sharding or handling "hotspots") Exponent.
Explain Your Logic: Review similar practice problems like "Building an in-memory database" or "Core banking logic" on sites like IGotAnOffer or Exponent to see how to structure your verbal walkthrough Exponent +1.
