I think they're talking about something at another level of scale and formality. I worked for Amazon too, but the "training" was more "toss you into the deep end and help as needed".

Don't get me wrong, I think trial by fire is largely a fine way of training, but it is very different.

Google has an actual, formalized Noogler course that you take when you first get there. This is closer to the model of training that exists at the large Asian megacorps - but think formalized, time-off, dedicated training courses rather than the ad hoc "tap your team lead on the shoulder when you need help" model of the modern American tech industry.
