I spent a few years in Cambridge and actually studied in Oxford for a bit.
In any case, Google Cloud is a very different beast from the rest of Google. For better or worse. And support engineers are yet another special breed. Us run-of-the-mill Googlers weren't allowed near any customers nor members of the general public.
My British don experience is based on 1 year of study abroad at Oxford in the 20th c. Also very smart people, but a much more timid sounding language (at least at first blush; under the self-deprecating general tone, there could be knives).
