Quantity of questions or quality of questions for interview & OA prep?

hey folks 👋 i’ve solved around 250 problems on leetcode and around total 430 questions of dsa across different platforms, and my striver dsa sheet is about 70% complete. now i’m kinda stuck wondering — should i: keep solving new questions to increase quantity and exposure, or focus on revising and mastering the problems i’ve already solved — understanding patterns, optimizing approaches, and ensuring i can solve them quickly under pressure? for those who’ve already gone through the interview grind — what worked better for you in the long run, especially for oa and sde interviews? https://preview.redd.it/7wfr3d1infzf1.png?width=1730&format=png&auto=webp&s=5794f334f14c307c513f1aab4b77551ba21b9bc2
