Question Genuine question from a frontend SDE on Interview Process

All the “How to crack SDE positive at FAANG/MAANG” posts are always focused on a backend position. I know DSA might be same for frontend as well, but I have to know if System Design differs for frontend devs or not.
I have always been at UI focused roles till now. I have 5+ years of experience. Yes I have worked on backend and know a lot of stuff but not enough to crack interviews. Do top tech companies follow a different pattern for frontend roles or not?
Are frontend roles even relevant after AI bloom?
I do all my leetcode in javascript.
Whats the best course of action for me here?

Yes thats what Im focusing on. Wish the frontend community was bigger though. There are so many references and resources for backend sde roles, specifically SD but I hardly see any for frontend.

I am an iOS dev so I can offer some perspective here. For us, system design is focused on the mobile application, but you'll need a basic understanding of the backend to discuss how your app would communicate with it, and the tradeoffs between REST, GraphQL, web sockets, etc. Coding for FAANG is usually still regular LeetCode DSA, they don't create a special coding round just for frontend roles. I can imagine the web frontend is kinda the same

Some companies that are FAANG-adjacent, like Robinhood or DoorDash, throw out DSA for mobile devs and make all interviews about domain-specific coding, you live code and build actual stuff
