What are they replacing it with? Back to prestigious university?
In fact, I'd say at least some of top tech companies are doing frontend interviews like this. Can confirm with firsthand experience for Facebook, Netflix, Amazon, Uber. Go a tier (or more) lower and it seems it's still just leetcode interviews though, barely any different from a general or backend track.
"implement a custom event emitter class in JavaScript" or "implement an image carousel component"...
...instead of something like "invert a binary tree".
Plus you'd get 2-3 rounds of these questions in lieu of the leetcode DS&A rounds. The (usually single) system design round would remain the same (albeit being something like implementing a UI component at a high and holistic level).
