This tripped me up because my brain kept wanting to go to software solutions.
Clarify the constraints and goal first, then propose a hardware-level workaround that treats Alexa as an external audio device. Walk through the signal chain, trade-offs, and safety considerations, and finish by outlining a minimal prototype and validation plan.
Pro tip: Acknowledge that this is a hack and emphasize safety and user experience over cleverness; interviewers value pragmatic risk assessment more than a perfect technical solution.
Ask questions to understand what 'no software integration' means (e.g., no API, no car OS access) and what the desired user experience is (voice control, music, navigation).
Identify where to tap into the car's audio system, such as AUX input, Bluetooth, or FM transmitter, and how to power the Alexa device.
Propose a concrete setup: Alexa device audio out to car AUX, power via USB adapter, and a mount for the device. Consider echo cancellation and microphone placement.
Discuss hands-free operation, minimizing driver distraction, and ensuring the setup doesn't interfere with critical car functions.
Outline a quick prototype using off-the-shelf parts, then test for audio quality, latency, and reliability, and iterate based on feedback.
