Our company has decided we no longer need whiteboard interviews as we just contract with Google for candidates' search history (filtered for technical issues only of course!).

(In case anyone thinks google sells search history retail: this is a joke...at least for now).

They wouldn't sell browsing histories; that data is a valuable asset. They would follow the model used by most "AI" products: an "AI"/"smart" service that launders candidates' history data into an opaque score. The hiring company's workload is reduced to mapping a score value onto their hiring plan, and Google will make a carefully worded claim that they are not selling personal information.

A shrewd distinction.
