Need advice regarding DSA

Context: This semester i did my Data Structures course in university, although it didn't feel like that much of a problem (maybe because i didn't do leetcode etc) and did just main main Data Structures, not a complete playlist on YouTube. Maybe the content which i covered in uni was almost 30-40% of the main playlists like kunal kushwaha and Striver Data Structures playlist. Now I am at semester break and then i will be in 4th semester and then there will be a course named Design and Analysis of Algorithms.

I wanted to ask that what should i do? Should i complete some YouTube playlist throughout the degree? Or something else? I have heard DSA is the main portion in job interviews.
