Need some advice for FAANG interviews as a 4 YOE dev.

Hello, I am a dev working at a small startup (7 LPA) with 4 YOE making apps and websites with angular/ionic/flutter. I have made cross platform apps, uploaded them to both the play store and app store and maintained them for clients. I am thinking of trying to apply for positions in FAANG companies. Will brushing up DSA and grinding leetcode be enough for me?
