Design an application that controls multiple smart-home device types (e.g., fan, TV) supporting generic ON/OFF commands common to all devices plus device-specific commands, extensibly.
Design an application that controls multiple smart-home device types, such as a fan and a TV. Every device supports generic commands common to all devices (turn on/off), and some devices support additional device-specific commands. The starter workspace includes one possible shared Device abstraction; assess whether to keep or refactor it, then clarify and state your own assumptions about the exact command set before designing.
Work in the provided coding workspace while explaining your decisions to the live interviewer. Validation may use inline tests, examples, comments, or a verbal walkthrough.
Practice this problem in the live coding workspace while the interviewer probes your clarification, implementation, trade-offs, and validation.
