I work in FAANG in a senior/tech lead engineering role. I don’t think unbroken ladder of latest gee-whiz frameworks and libraries is even remotely accurate of what developers in these companies care about or need.

If anything, wanting to adopt the latest and “greatest” is usually a sign of an inexperienced engineer.

If you’re at FAANG, especially at a team that is optimizing for throughput or scale, you’ll care more about design trade offs and performance, availability, and resiliency concerns as opposed to the latest framework. If anything, something tried and true that’s been out a long while and vetted out is a lesser risk than something released in the past year or two. In other words, maturity is an important factor (the weight may depend given your other considerations).

Seconded. My FAANG team doesn't use frameworks that would be recognizable outside the company, only internal ones. My interview didn't involve any frameworks, only basic computer science, design, and problem-solving.
