Interesting on the relevancy stand point. As an iOS developer, I had to learn a whole new set of skills for the interviews... I can count on one hand the number of times I needed to use techniques needed for the algorithm questions. I feel like the skills around making large scale apps is more about being able to reason about large scale projects and keeping everything clean and tidy.

I haven’t really met anyone yet who could talk the talk but couldn’t write code... I’ve definitely met people who have tried... maybe I have a good BS detector, or maybe I’ve been lucky? All people I’ve hired without doing the BST/linked list/DP problems, Ended up working out great. They probably can’t do those problems still, but they can code a damn good app. Guess it goes back to not caring about false negatives
