How about all the embedded engineers who go on to become RoR engineers because it pays much better?

Google is probably willing to train people too, which might be a difference for you. C++ isn't that fun of a language compared to others too.

Nah. Google doesn't "train" per se. They expect that you already know your shit pretty well when you get hired, or else they just don't hire you. From there on out you're on your own. No one will "train" you specifically, although opportunities are sometimes available. In particular, no one will specifically train you to write tight code. Your CLs will just get rejected until you learn that on your own. Source: spent 8 years at Google.
