Depends on what you do at Google.
Google Guava is a data-structure/algorithms-heavy great Java library.
Dart and Golang are programming languages. I'd imagine you have to know how to write a compiler etc and the standard library definitely has sections for data-structure and algorithms.
They pay tons of money and prefer people to stick around and do different things within the company so I guess that's why they set the bar high for that specific section of skillset (algorithms and data structure).
Some people are willing to go through that for the Money, Prestige, and hopefully the experience. Some people don't. That's life.
