I presume the candidate needs to provide his address. Have someone else google street map it, and then at some point ask "what is the color of your front door?" If he takes more than 5 seconds to answer it, end the interview.
Within 5 seconds? I doubt they could load google maps that fast.
> Also I have no idea what my front door color is
No hire!
We mostly enter through a side door, and the back door.
... and I also couldn't tell you what color either of those are.
An answer that's also suspicious, because it means they know what you're implying by asking, and they've prepared for it.
In fact I’d bet a good chunk of people, especially tech literate people, could tell you the most recent date of Google Street View for their house.
