TODO List Example Problem

Premise

Build a simple TODO list application that helps a user capture, organize, and complete short tasks. The exact product scope is intentionally small so the implementation can reveal practical engineering judgment: data modeling, interaction design, state management, and code organization.

Candidate-Facing Stub

You are building the first version of a TODO list tool. A useful solution should let a user:

• Add a task with a short title
• Mark a task complete or incomplete
• Edit and delete tasks
• See active and completed tasks clearly

Possible Extensions

• Persist tasks between reloads
• Add filtering or sorting
• Add due dates or priorities
• Add keyboard-friendly interactions
• Add tests for core behavior

TODO
