Upskilling vs interview prep

I feel there is a serious disconnect between what we do in our day to day job vs what's asked in interviews. I like learning new tech but I hate doing interview prep like doing Leetcode, LLD, HLD. I would much rather talk about the work that I am doing, my personal projects, etc during interviews but all high paying jobs like FAANG/big startups will always ask DSA and all during interviews regardless.

How should I spend my time in learning new tech vs doing interview prep as I feel the interviews have gotten much harder and it takes a long time to get proficient in DSA, LLD, HLD?
