he closest Google typically gets to brainteasers is questions that are actually estimation or, more commonly, market-sizing questions. These include questions along the lines of “How many gas stations are there in Manhattan?” or “How would you estimate the revenue for Google Ads?”

It’s about breaking down a problem, making reasonable assumptions, and doing a little bit of arithmetic.
