I take it the commenter is talking more about business roles than engineering. To be sure, there are unique engineering problems that massive scale companies face.

For business leadership roles though, you often see people trying to coast on successes that they had little role in creating.

To be fair though, there are great leaders at all kinds of companies. And the success, money, and potential impact one can have at companies like Intel and Google attracts a lot of talented people. I think it's just a matter of not automatically assuming people are great just because of what's on their resume.

I work on Google Fiber and am continually impressed with the business folks too. It is hard work to dig up streets and install fiber, negotiate agreements necessary to provide TV service, provide high-quality customer service, etc.

Google (er, Alphabet) has a lot of employees, and maybe not every single one is the best in their field (they hired me), but overall I think that a Google tenure on your resume can be a meaningful positive signal for future employees.

At the very least, maybe they'll steal some of the really good ideas around here, like an internal social network. (Available for anyone using Google Apps, not just us ;)
