My experience with Google (in the UK) was an interviewer who asked a very similar question, among a number where he was clearly unprepared to deal with answers that weren't 100% as expected, and asked questions that had basically no relevance to the role.
The experience was so bad that afterward I sent a lengthy email to the recruiter thanking her but pointing out I expected to fail the interview because the interviewer insisted on things that were wrong or irrelevant and set out why as a courtesy so they could address it for the future.
I was rung up and was told the recruiter had gotten the interview set aside, and offered to just have me bypass the technical interview and wanted to move on to an interview with the hiring manager.
In the end I declined, as the first interviewer would have been one of the people I'd have managed, and I just did not want to deal with a team with a person like that, and the whole process was just excruciatingly slow to the point I had offers on the table before they could line up an interview.
It seemed to be a process optimised for people who either desperately want to work specifically at Google, or doesn't have alternatives.
I kept getting calls from Google recruiters for years after that and kept recounting my past experience and asking if they could provide a better experience this time around.
I have had worse interview experiences than Google, including one where I halted a phone interview halfway through and told them they'd shown me I didn't want to work there, but Google is pretty high on my list of places I'm not particularly interested in interviewing.
