But why would the homework for a React job include RB trees? It seems some interviews add unrelated technical questions.

Not that I agree with it, but they're testing general CS knowledge at that point. What if they decided to switch from React to something else entirely? Have you made your future employer confident enough that you're competent enough to handle that and more?

Because switching from react to angular requires knowledge of RB trees. /s

I get what you're saying, but sometimes interview questions are too far removed from the position.
