I left an interview early too, with Google in fact. I told them I obviously did not fit in their culture at least for that very position (SRE) , as we had divergent views, and that I wanted to abort the interview process. No need for them or I to lose time if I was going to refuse anyway.

The guy (technical person) was shocked, as if this was impossible. He also insisted more than 5 times to continue with the process, which, I refused.

Later on, they contacted me, telling me that they marked me as "failed interview process" (ie: do not hire in the future).

That told only one thing, that indeed, I wasn't a fit for that culture - probably at any position then.
