This has zero to do with OP’s question, which is specifically about its desirability for potential future employers. Whom does it serve for you to ask this question?
I use a few Google products and their UX strikes me as weak. Documentation for developer tools that I need to use is often painful as well. That's not training, but if you're not good at explaining your design and code to another coder it doesn't bode well for explaining higher-level principles. If the hiring decision were up to me, I'd discount it.
