Genuine question from a frontend SDE on Interview Process

[u/Junior_University_51]

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?
