I have never touched leetcode until today. just got laid off, preparing for my next interview. I already have a good study plan for Android (system design, coroutines, etc). What I’m missing is DSA and leetcode. I already did a few binary search problems. what else should I know or be doing?

I don’t want to overshoot, but I would like to be competent in interviews. What topics would you suggest I learn and how deep should I dive in said topics?
