I will have this soon but I don't know how to approach it and there is no resource I can find.
For example, this is just my guess, if the company is Amazon then they can ask "Design Alexa device" or "Design Ring doorbell".
Then, from my knowledge by learning about a general system design interview preparation,

1. Ask the requirement and talk enough with the interviewer to clarify the goal
2. Consider the scalability and restriction
3. Draw the whole components on the white board and add with discussion

But how can apply this to the embedded system design too?

If anybody had an experience this with FAANG or other companies, please advise.
Also please share if you know any website or youtube videos related to this.

Or the interview direction can be totally different way?
Such as, not designing a system or device, a question like "print something with using two threads".
I have no idea, please help.

Thanks.
