If this were remotely true, there wouldn't have huge layoff rounds. The opposite is true: they hire thousands upon thousands of people and teach them how to build scalable software, and then set them loose. I'm frankly surprised by the lack of competition, but I suppose that's gated at multiple levels (visas, personal risk, funding, network effects, etc)
> Don't they screen to hire people who already know that?
There was a time when big tech widely hired dor entry-level jobs.
Also, cramming for the design portion of an interview, and doing it for real, and interacting with the architects/design documents are 2 very different things
