Design an Employee Management System
Design an internal employee management system with the following capabilities:
Functional Requirements
- CRUD for Employees:
- Create and update employee profiles, including name, title, department, and manager.
- Deactivate or terminate employee accounts.
- Organizational Structure Queries:
- Retrieve an employee's direct manager.
- Retrieve an employee's direct reports.
- Retrieve an employee's complete reporting chain (up to the CEO).
- Retrieve an employee's entire reporting subtree (all indirect reports).
Non-Functional Requirements / Discussion Points
- Handle high concurrency for both reads and writes.
- Ensure correctness under concurrent updates.
- Address locking and consistency concerns, specifically avoiding organizational cycles and lost updates.
- Design the API, including endpoints, payloads, and versioning.
- Discuss data storage choices and schema design.
Explain your design and the trade-offs involved, particularly focusing on how you would implement efficient reporting-line queries.

Core dilemma
Balancing the complexity of representing and querying a hierarchical, mutable graph structure (the org chart) against the need for high availability and low latency for both updates and complex traversals.
