Most of us work at places that don a lot of things differently to Google I suspect.
There's a _huge_ difference between how on-call works in a dozen or so person startup, and hundred or two person single timezone business, and a thousands of engineers across almost all timezones.
I _dream_ of working at a place that has follow-the-sun teams of SDEs and SRDs across 3 or 4 timezones. I have not yet worked at a place large enough to have on call secondaries, I've only worked places where the only on call escalation is that the on call person's manager gets paged (and angry) if the on call person hasn't responded within the SLA. (And I've been both the on call person and the manager in that scenario in several different organisations...)
